* Hash function class that can take a data chunk of any predetermined length. The hash function
* used is the One-at-a-Time Hash (http://burtleburtle.net/bob/hash/doobs.html).
*
* Keys are computed from Entry objects. Entry must be fully ordered by a member:
* int compare(const GrTBinHashKey<Entry, ..>& k);
* which returns negative if the Entry < k, 0 if it equals k, and positive if k < the Entry.
* Additionally, Entry must be flattenable into the key using setKeyData.

* This class satisfies the requirements to be a key for a GrTHashTable.
