-/**
-*
-* Parse for URLS in the source text.
-*
-* Various URL markings are supported: inline (the URL by itself),
-* numbered or footnote reference (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
-* numbered -- [http://example.com]
-* described -- [http://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
