/**
 * Factory (and decorator used when extending LimeComboBox) that creates the three
 *  types of of "combo boxes" we use in the LimeWire UI.
 *  
 *  Types:
 *  <xmp>
 *    Full - The full combo box type with a selectable slot.  These work mostly 
 *            the same as regular JComboBoxes.  
 *            ie.  Search category dropdown.
 *            
 *   Mini - These boxes act more as toggles for drop down menu's of actions.
 *           ie.  The More button, the from widget, etc.
 *  
 *  Colour Scheme:
 *  
 *    Dark - Use the a "dark" colour scheme.  These are usually found
 *                        ontop of dark panels such at the header bars
 *                      
 *    Light - Use a ligher colour sheme.  These are usually found on top of 
 *                        lightly coloured panels.  In this case mostly 
 *                        the top search bar
 *                        
 *                        
 *                        
 * </xmp>
