+/**
+*
+* 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
