- * ClassLoader implements a PSR-0 class loader

- *
- *     $loader = new \Composer\Autoload\ClassLoader();
- *
- *     // register classes with namespaces
- *     $loader->add('Symfony\Component', __DIR__.'/component');
- *     $loader->add('Symfony',           __DIR__.'/framework');

- *     $loader->register();

- *     $loader->setUseIncludePath(true);
- *
- * In this example, if you try to use a class in the Symfony\Component
- * namespace or one of its children (Symfony\Component\Console for instance),
- * the autoloader will first look for the class under the component/
- * directory, and it will then fallback to the framework/ directory if not
- * found before giving up.
- *
- * This class is loosely based on the Symfony UniversalClassLoader.

-PHP Markdown Lib 1.3 - 11 Apr 2013
-
-by Michel Fortin  
-<http://michelf.ca/>
-
-based on Markdown by John Gruber  
-<http://daringfireball.net/>
-
-
-Introduction
-------------
-
-This is a library package that includes the PHP Markdown parser and its 
-sibling PHP Markdown Extra which additional features.
-
-Markdown is a text-to-HTML conversion tool for web writers. Markdown
-allows you to write using an easy-to-read, easy-to-write plain text
-format, then convert it to structurally valid XHTML (or HTML).
-
-"Markdown" is two things: a plain text markup syntax, and a software 
-tool, written in Perl, that converts the plain text markup to HTML. 
-PHP Markdown is a port to PHP of the original Markdown program by 
-John Gruber.
-
-PHP Markdown can work as a plug-in for WordPress, as a modifier for
-the Smarty templating engine, or as a replacement for Textile
-formatting in any software that supports Textile.
-
-Full documentation of Markdown's syntax is available on John's 
-Markdown page: <http://daringfireball.net/projects/markdown/>
-
-
-Requirement
------------
-
-This library package requires PHP 5.3 or later.
-
-Note: The older plugin/library hybrid package for PHP Markdown and
-PHP Markdown Extra is still maintained and will work with PHP 4.0.5 and later.
-
-Before PHP 5.3.7, pcre.backtrack_limit defaults to 100 000, which is too small
-in many situations. You might need to set it to higher values. Later PHP 
-releases defaults to 1 000 000, which is usually fine.
-
-
-Usage
------
-
-This library package is meant to be used with class autoloading. For autoloading 
-to work, your project needs have setup a PSR-0-compatible autoloader. See the 
-included Readme.php file for a minimal autoloader setup. (If you don't want to 
-use autoloading you can do a classic `require_once` to manually include the 
-files prior use instead.)
-
-With class autoloading in place, putting the 'Michelf' folder in your 
-include path should be enough for this to work:
-
-	use \Michelf\Markdown;
-	$my_html = Markdown::defaultTransform($my_text);
-
-Markdown Extra syntax is also available the same way:
-
-	use \Michelf\MarkdownExtra;
-	$my_html = MarkdownExtra::defaultTransform($my_text);
-
-If you wish to use PHP Markdown with another text filter function 
-built to parse HTML, you should filter the text *after* the `transform`
-function call. This is an example with [PHP SmartyPants][psp]:
-
-	use \Michelf\Markdown, \Michelf\SmartyPants;
-	$my_html = Markdown::defaultTransform($my_text);
-	$my_html = SmartyPants::defaultTransform($my_html);
-
-All these examples are using the static `defaultTransform` static function 
-found inside the parser class. If you want to customize the parser 
-configuration, you can also instantiate it directly and change some 
-configuration variables:
-
-	use \Michelf\MarkdownExtra;
-	$parser = new MarkdownExtra;
-	$parser->fn_id_prefix = "post22-";
-	$my_html = $parser->transform($my_text);

-
-To learn more, see the full list of [configuration variables].
-
- [configuration variables]: http://michelf.ca/project/php-markdown/configuration/
-
-
-Public API and Versionning Policy
----------------------------------
-
-Version numbers are of the form *major*.*minor*.*patch*.
-
-The public API of PHP Markdown consist of the two parser classes `Markdown`
-and `MarkdownExtra`, their constructors, the `transform` and `defaultTransform`
-functions and their configuration variables. The public API is stable for
-a given major version number. It might get additions when the minor version
-number increments.
-
-**Protected members are not considered public API.** This is unconventionnal 
-and deserves an explanation. Incrementing the major version number every time 
-the underlying implementation of something changes is going to give nonsential 
-version numbers for the vast majority of people who just use the parser. 
-Protected members are meant to create parser subclasses that behave in 
-different ways. Very few people create parser subclasses. I don't want to 
-discourage it by making everything private, but at the same time I can't 
-guarenty any stable hook between versions if you use protected members.
-
-**Syntax changes** will increment the minor number for new features, and the 
-patch number for small corrections. A *new feature* is something that needs a 
-change in the syntax documentation. Note that since PHP Markdown Lib includes
-two parsers, a syntax change for either of them will increment the minor 
-number. Also note that there is nothigng perfectly backward-compatible with the
-Markdown syntax: all inputs are always valid, so new features always replace
-something that was previously legal, although generally non-sensial to do.
-
-
-Bugs
-----
-
-To file bug reports please send email to:
-<michel.fortin@michelf.ca>
-
-Please include with your report: (1) the example input; (2) the output you
-expected; (3) the output PHP Markdown actually produced.
-
-If you have a problem where Markdown gives you an empty result, first check 
-that the backtrack limit is not too low by running `php --info | grep pcre`.
-See Installation and Requirement above for details.
-
-
-Version History
----------------
-
-PHP Markdown Lib 1.3 (11 Apr 2013):
-
-This is the first release of PHP Markdown Lib. This package requires PHP 
-version 4.3 or later and is designed to work with PSR-0 autoloading and, 
-optionally with Composer. Here is a list of the changes since 
-PHP Markdown Extra 1.2.6:
-
-*	Plugin interface for Wordpress and other systems is no longer present in
-	the Lib package. The classic package is still available if you need it:
-	<http://michelf.ca/projects/php-markdown/classic/>
-
-*	Added `public` and `protected` protection attributes, plus a section about
-	what is "public API" and what isn't in the Readme file.
-
-*	Changed HTML output for footnotes: now instead of adding `rel` and `rev`
-	attributes, footnotes links have the class name `footnote-ref` and
-	backlinks `footnote-backref`.
-
-*	Fixed some regular expressions to make PCRE not shout warnings about POSIX
-	collation classes (dependent on your version of PCRE).
-
-*	Added optional class and id attributes to images and links using the same
-	syntax as for headers:
-
-		[link](url){#id .class}  
-		![img](url){#id .class}
-	
-	It work too for reference-style links and images. In this case you need
-	to put those attributes at the reference definition:
-
-		[link][linkref] or [linkref]  
-		![img][linkref]
-		
-		[linkref]: url "optional title" {#id .class}
-
-*	Fixed a PHP notice message triggered when some table column separator 
-	markers are missing on the separator line below column headers.
-
-*	Fixed a small mistake that could cause the parser to retain an invalid
-	state related to parsing links across multiple runs. This was never 
-	observed (that I know of), but it's still worth fixing.

- * the i18n extension is now part of the Twig Extensions repository

- * added priority to node visitors
-
-* 0.9.9 (2010-11-28)
-
-Backward incompatibilities:

-     {{ foo|odd }} must now be written {{ foo is odd }}
- * the "safe" filter has been renamed to "raw"

-        sub-nodes are now accessed via getNode() (instead of property access)
-        attributes via getAttribute() (instead of array access)
- * the urlencode filter had been renamed to url_encode
- * the include tag now merges the passed variables with the current context by default
-   (the old behavior is still possible by adding the "only" keyword)
- * moved Exceptions to Twig_Error_* (Twig_SyntaxError/Twig_RuntimeError are now Twig_Error_Syntax/Twig_Error_Runtime)
- * removed support for {{ 1 < i < 3 }} (use {{ i > 1 and i < 3 }} instead)
- * the "in" filter has been removed ({{ a|in(b) }} should now be written {{ a in b }})
-

- * fixed unary expressions ({{ not(1 or 0) }})
- * fixed child templates (with an extend tag) that uses one or more imports
- * added support for {{ 1 not in [2, 3] }} (more readable than the current {{ not (1 in [2, 3]) }})
- * escaping has been rewritten

-
-* 0.9.8 (2010-06-28)

-
-* 0.9.7 (2010-06-12)

- * removed the sandboxed attribute of the include tag (use the new sandbox tag instead)
- * refactored the Node system (if you have custom nodes, you will have to update them to use the new API)
-
- * added self as a special variable that refers to the current template (useful for importing macros from the current template)

-
-If you have created NodeTransformer classes, you will need to upgrade them to
-the new interface (please note that the interface is not yet considered
-stable).
-
- * fixed list nodes that did not extend the Twig_NodeListInterface
- * added the "without loop" option to the for tag (it disables the generation of the loop variable)
- * refactored node transformers to node visitors
- * fixed automatic-escaping for blocks
- * added a way to specify variables to pass to an included template
- * changed the automatic-escaping rules to be more sensible and more configurable in custom filters (the documentation lists all the rules)
- * improved the filter system to allow object methods to be used as filters
- * changed the Array and String loaders to actually make use of the cache mechanism
- * included the default filter function definitions in the extension class files directly (Core, Escaper)
- * added the // operator (like the floor() PHP function)
- * added the .. operator (as a syntactic sugar for the range filter when the step is 1)
- * added the in operator (as a syntactic sugar for the in filter)
- * added the following filters in the Core extension: in, range
- * added support for arrays (same behavior as in PHP, a mix between lists and dictionaries, arrays and hashes)
- * enhanced some error messages to provide better feedback in case of parsing errors
-
-* 0.9.4 (2009-12-02)
-
-If you have custom loaders, you MUST upgrade them for this release: The
-Twig_Loader base class has been removed, and the Twig_LoaderInterface has also
-been changed (see the source code for more information or the documentation).
-
- * added support for DateTime instances for the date filter
- * fixed loop.last when the array only has one item
- * made it possible to insert newlines in tag and variable blocks
- * fixed a bug when a literal '\n' were present in a template text
- * fixed bug when the filename of a template contains */
- * refactored loaders
-
-* 0.9.3 (2009-11-11)
-
-This release is NOT backward compatible with the previous releases.
-
-  The loaders do not take the cache and autoReload arguments anymore. Instead,
-  the Twig_Environment class has two new options: cache and auto_reload.
-  Upgrading your code means changing this kind of code:
-
-      $loader = new Twig_Loader_Filesystem('/path/to/templates', '/path/to/compilation_cache', true);
-      $twig = new Twig_Environment($loader);
-
-  to something like this:
-
-      $loader = new Twig_Loader_Filesystem('/path/to/templates');
-      $twig = new Twig_Environment($loader, array(
-        'cache' => '/path/to/compilation_cache',
-        'auto_reload' => true,
-      ));
-
- * deprecated the "items" filter as it is not needed anymore
- * made cache and auto_reload options of Twig_Environment instead of arguments of Twig_Loader
- * optimized template loading speed
- * removed output when an error occurs in a template and render() is used
- * made major speed improvements for loops (up to 300% on even the smallest loops)
- * added properties as part of the sandbox mode
- * added public properties support (obj.item can now be the item property on the obj object)
- * extended set tag to support expression as value ({% set foo as 'foo' ~ 'bar' %} )
- * fixed bug when \ was used in HTML
-
-* 0.9.2 (2009-10-29)
-
- * made some speed optimizations
- * changed the cache extension to .php
- * added a js escaping strategy
- * added support for short block tag
- * changed the filter tag to allow chained filters
- * made lexer more flexible as you can now change the default delimiters
- * added set tag
- * changed default directory permission when cache dir does not exist (more secure)
- * added macro support
- * changed filters first optional argument to be a Twig_Environment instance instead of a Twig_Template instance
- * made Twig_Autoloader::autoload() a static method
- * avoid writing template file if an error occurs
- * added $ escaping when outputting raw strings
- * enhanced some error messages to ease debugging
- * fixed empty cache files when the template contains an error
-
-* 0.9.1 (2009-10-14)
-
-  * fixed a bug in PHP 5.2.6
-  * fixed numbers with one than one decimal
-  * added support for method calls with arguments ({{ foo.bar('a', 43) }})
-  * made small speed optimizations
-  * made minor tweaks to allow better extensibility and flexibility
-
-* 0.9.0 (2009-10-12)
-
- * Initial release

-/**

- * To help debugging template issues, this class tracks the original template

- * Whenever possible, you must set these information (original template name

- * these information are not available from where you throw the exception, then

- * and/or the filename is set to null). As this is a costly operation, this
- * can be disabled by passing false for both the filename and the line number
- * when creating a new instance of this class.
