/**
 * G7CollationTest is a third level test class.  This test performs the examples 
 * mentioned on the Taligent international demos web site.  
 * Sample Rules: & Z < p , P 
 * Effect :  Making P sort after Z.
 *
 * Sample Rules: & c < ch , cH, Ch, CH 
 * Effect : As well as adding sequences of characters that act as a single character (this is
 * known as contraction), you can also add characters that act like a sequence of
 * characters (this is known as expansion).  
 * 
 * Sample Rules: & Question'-'mark ; '?' & Hash'-'mark ; '#' & Ampersand ; '&' 
 * Effect : Expansion and contraction can actually be combined.  
 * 
 * Sample Rules: & aa ; a'-' & ee ; e'-' & ii ; i'-' & oo ; o'-' & uu ; u'-'
 * Effect : sorted sequence as the following,
 * aardvark  
 * a-rdvark  
 * abbot  
 * coop  
 * co-p  
 * cop
