/**

* preg_replace (from PHP) in JavaScript!
|

*
|

* This is basically a pattern replace. You can use a regex pattern to search and

* another for the replace. For more information see the PHP docs on the original
|

* function (http://php.net/manual/en/function.preg-replace.php), and for more on
|
||||
* JavaScript flavour regex visit http://www.regular-expressions.info/javascript.html
|
||||
*
|
||||
* NOTE: Unlike the PHP version, this function only deals with string inputs. No arrays.

|

* This function parses a small subset of the Markdown language as defined by

* [John Gruber](http://daringfireball.net/projects/markdown). It's very basic
|

* for the rest of the language in the near future.
|
