/**
*
* Parse for URLS in the source text.
*
* Various URL markings are supported: inline (the URL by itself),
* inline (where the URL is enclosed in square brackets), and named
* reference (where the URL is enclosed in square brackets and has a
* name included inside the brackets). E.g.:
*
* inline -- http://example.com
* undescribed -- [http://example.com]
* described -- [http://example.com Example Description]
* described -- [http://www.example.com|Example Description]
*
* When rendering a URL token, this will convert URLs pointing to a .gif,
* .jpg, or .png image into an inline <img /> tag (for the 'xhtml'
* format).
*
* Token options are:
*
* 'type' => ['inline'|'footnote'|'descr'] the type of URL
*
* 'href' => the URL link href portion
*
* 'text' => the displayed text of the URL link
