Detailed Description

Carma Singleton Adaptor class.

Initial motivation was provided by work done by Eric Crahen on the ZThreads library. Based strongly on Loki::Singleton by Andrei Alexandrescu and somewhat on the ACE_Singleton by Doug Shmidt and others. The Loki and ACE implementations are far superior to what I've provide here, however, using either of these would have required bringing in the whole package AND coding paradigm. In general, these packages threading models would interfere with Carma thread constructs so I've opted for a minimal homegrown implementation that should satisfy most common uses.
