#
# Program to sort a string delimited by any character
# Advantage:
# - Highly portable, tested on Python 2.7 and 3.5
# - Highly customizable and easy to use.
#   Instantiate the class with your own defaults
#
# Example:
#
#    fixlist = sortByTokens(False, ',')
#    print( fixlist( 'B , b , a , A' ) )
#
#    ['A', 'B', 'a', 'b']

    sortByTokens class takes two arguments during instantiation

    ignoreCase, set to True by default
    delimter, set to '>' by default. Must be a single character

    Usage : sortByTokens()(<string>)
