/**

 * PreferenceApp is used to analyze a category of items that a group

 * of people have rated.  A user is grouped to be analyzed in the group by

 * 1) having rated at least one item in the database and 2) matching the optional 

 * criteria for declaring a budget on their homepage.  

 *

 * An example of a budget decleration would be "TotalSoda: 50" on my homepage.

 *

 * PreferenceApp will output a matrix style table shows "how much" fractionally 

 * a group of people prefer an item over other items.  For example, if my soda 

 * budget is 100 then PreferenceApp might assign 20 units of my budget to Moutain Dew.

 *

 * Author: mcassano circa April 2004

 *

 * Usage:

 * <?plugin PreferenceApp category="Soda" pageLabel="TotalSoda" roundCalc="true" ?>
