    MTMultiSelect: An widget to make more user friendly interfaces
    for a multiselect box, using Mootools    
    
    Usage:
    
    Link to this file, then add 
    
    window.addEvent('domready', function (){
         $$('.multiselect').each(function(multiselect){
            new MTMultiWidget({'datasrc': multiselect});
        });
            
    });
    
    to your page, where '.multiselect' is a selector that picks out a class of
    <select MULTIPLE> elements. This element acts as the data source for the
    widget. Then create a css file and style the widget however you'd like. 
    
    Options: add these to the object you pass to the MTMultiWidget constructor.
    Only datasrc is required.
    
    widgetcls:
    The css class applied to your final widget.
    Default is 'mtmultiselect'
    
    datasrc:
    A select multiple dom object
    
    selectedcls:
    The css class of the selected list item.
    Default is  'selected'
    
    paginator_on_bottom:
    Determines placement of paginator, true or false.
    Default is true
    
    items_per_page:
    Determines how many items to show on a single page.
    Default is 10.
    
    case_sensitive:
    Determines if the filter form is case_sensitive or not
    Default is False
