Detailed Description

Defines a Weak version of Token class with a fixed, constant hash value. Hashes are calculated using the cityhash_gl hash functions. It is designed as a robust key for hash tables. The difference between this class and the regular Token class is that this one only stores the hash value, making it better suited for querying over network connections.
