Etomite Tagcloud script

This TagCloud script is useless “as-is” but it will create a tagcloud.
/****************************************************
* Name: Tagcloud
* Version: 0.2
* Desc: Displays the containing words of documents in a "tag cloud"
* Based on the Tagcloud 1.1. snippet created by Marc Hinse, [email protected]
* Converted to EtomiteCMS by Bogge, bogge.com
*
* Change 0.1 => 0.2 Removed explode $parent and optimized sql query. Thanks to adamzyg.
*
* Usage: [[tagcloud?parent=`1,3,5,6,7,14`&min=`3`&landing=`12`
* Parameters: 
* 	parent: comma separated list of the folders that conatin the documents which are to be counted
*	min: Minimum occurrences of a word to be displayed
*	landing: the id of your search result page. If you don´t have one, create it like: [!FlexSearchForm?FSF_showResults=`1` &FSF_showForm=`0`!]
*   (this is required for linking the tags)
