Detailed Description

Defines template helper classes for thread-local storage.

The helpers here provide an implementation of thread-local storage which allows for non-static dynamic memory management as well as element iteration. This extra functionality makes these containers much slower than the builtin thread_local and should only be used when needed.

Todo:

Should we optimize these implementations for non-MT environments? One could alternatively just optimze the clients where necessary. I could replace these classes with a simple pointer wrapper if ATHENAHIVE and G4MULTITHREADED are not defined, but the map iteration functionality would need an awkward implementation.
