     * tags
     * This object contains a list of tags that your code will be able to understand.
     * Each tag object has the following properties:
     *
     *   openTag - A function that takes in the tag's parameters (if any) and its
     *             contents, and returns what its HTML open tag should be.
     *             Example: [color=red]test[/color] would take in "=red" as a
     *             parameter input, and "test" as a content input.
     *             It should be noted that any BBCode inside of "content" will have
     *             been processed by the time it enter the openTag function.
     *
     *   closeTag - A function that takes in the tag's parameters (if any) and its
     *              contents, and returns what its HTML close tag should be.
     *
     *   displayContent - Defaults to true. If false, the content for the tag will
     *                    not be displayed. This is useful for tags like IMG where
     *                    its contents are actually a parameter input.
     *
     *   restrictChildrenTo - A list of BBCode tags which are allowed to be nested
     *                        within this BBCode tag. If this property is omitted,
     *                        any BBCode tag may be nested within the tag.
     *
     *   restrictParentsTo - A list of BBCode tags which are allowed to be parents of
     *                       this BBCode tag. If this property is omitted, any BBCode
     *                       tag may be a parent of the tag.
     *
     *   noParse - true or false. If true, none of the content WITHIN this tag will be
     *             parsed by the XBBCode parser.
     *
     *
     *
     * LIMITIONS on adding NEW TAGS:
     *  - Tag names should be alphanumeric (including underscores) and all tags should have an opening tag
     *    and a closing tag.
     *    The [*] tag is an exception because it was already a standard
     *    bbcode tag. Technecially tags don't *have* to be alphanumeric, but since
     *    regular expressions are used to parse the text, if you use a non-alphanumeric
     *    tag names, just make sure the tag name gets escaped properly (if needed).
