Bittree v1.1

This release cleans up the Bittree source code, and makes some changes to the class hierarchy. Primarily, the Ref class has been replaced throughout, mostly by std::shared_ptr.

Bittree v1.0

This is basically the original Bittree package as written by John Bachan, with a test suite implemented to verify its functionality. In addition various compiler warnings have been addressed. A Bittree library could be built from this release and incorporated into an application or AMR package.

Future releases will focus on simplifying the C++ facing interface, as well as simplifying implementation details where appropriate.

Original Bittree

This is the original Bittree source code, copied over from Flash-X. A Unit Test has been implemented so future changes can be easily tested.
