    Generate small Spot-It decks by brute force searching for
    the exact cover of pairs of cards which share a symbol.

''' Case-insensitive string class

    A string class that uses lower-case hashing and comparisons.
    It also uses case-insensitive comparison when compared with 
    normal `str` strings.
    
    CIStr defines all 6 rich comparison methods, although only
    the `__eq__` method is needed for dictionary and set use.
