Pysuffix with utility functions

Implementation of suffix array (similar function as suffix tree, see wikipedia) in python, derived from https://code.google.com/p/pysuffix/

Utility function is added to show simple application of searching substring and finding longest repeating substring.

Usage

import suffixArrayApplications as saApp
s = 'aaaabcaa'
occurance = saApp.search('aa', s)
self.assertEquals(occurance, [0, 1, 2, 6])
