Log:

Add base ReferenceCounter class for use with objects that exist in
multiple locations as a shared pointer.  When the reference count hits
zero, the object will self delete.

Add a ReferenceLocker as a context manager, which will increment the
counter on creation, and decrement on destruction.

Added:
