-"""
-This example shows how to use the class PerfHash.
-
-This class is designed for creating perfect hash tables at run time,
-which should be avoided, in particulat inserting new keys is
-prohibitively expensive since a new perfect hash table needs to be
-constructed. However, this class can be usefull for testing.
-
-For practical programming purposes in Python the class PerfHash
-should never be used because Python's built-in dictionary is very
-efficient and always faster than PerfHash.
