Detailed Description

Maintain a mapping of strings to 64-bit ints.

Mar 2007 We map from strings to integer keys using a hash function. We keep a table of hashed strings so that we can later return the string given the key. We allow registering additional key->string mappings as well, as long as there aren't collisions. We also keep an auxiliary int that gets hashed along with the string.

A string can be marked as ‘transient’ (using SG::transientKey). If we encounter a hash collision while inserting a transient key, we do not fail, but instead use find an alternate hash for it.
