+	// Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
+	//
+	// Solution:
+	//
+	// We assume the radius of the polygon is half the size of the canvas at first
+	// at each index we check if the text overlaps.
+	//
+	// Where it does, we store that angle and that index.
+	//
+	// After finding the largest index and angle we calculate how much we need to remove
+	// from the shape radius to move the point inwards by that x.
+	//
+	// We average the left and right distances to get the maximum shape radius that can fit in the box
+	// along with labels.
+	//
+	// Once we have that, we can find the centre point for the chart, by taking the x text protrusion
+	// on each side, removing that from the size, halving it and adding the left x protrusion width.
+	//
+	// This will mean we have a shape fitted to the canvas, as large as it can be with the labels

+	// We average the left and right distances to get the maximum shape radius that can fit in the box

+	//
+	// Once we have that, we can find the centre point for the chart, by taking the x text protrusion
+	// on each side, removing that from the size, halving it and adding the left x protrusion width.

+ * Tag-closer extension for CodeMirror.
+ *
+ * This extension adds an "autoCloseTags" option that can be set to
+ * either true to get the default behavior, or an object to further
+ * configure its behavior.
+ *
+ * These are supported options:
+ *
+ * `whenClosing` (default true)
+ *   Whether to autoclose when the '/' of a closing tag is typed.
+ * `whenOpening` (default true)
+ *   Whether to autoclose the tag when the final '>' of an opening
+ *   tag is typed.
+ * `dontCloseTags` (default is empty tags for HTML, none for XML)
+ *   An array of tag names that should not be autoclosed.
+ * `indentTags` (default is block tags for HTML, none for XML)
+ *   An array of tag names that should, when opened, cause a
+ *   blank line to be added inside the tag, and the blank line and
+ *   closing line to be indented.
+ * `emptyTags` (default is none)
+ *   An array of XML tag names that should be autoclosed with '/>'.
+ *
+ * See demos/closetag.html for a usage example.
