/**
* 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.
*
* See demos/closetag.html for a usage example.
