Rather than printing them to stderr directly the parser now keeps a Vector<Error>, which allows the "owner" of the parser to consume them individually after parsing. The Error struct has a message, line number, column number and a to_string() helper function to format this information into a meaningful error message. The Function() constructor will now include an error message when throwing a SyntaxError.
