Oct 22, 2015

v20131012:

- Fixed a minor sizing problem which caused the right/bottom hex edges to get truncated in some cases.

- More internal work on exporting the underlying JSON data, but it is not yet exposed to users.

v20130922:

- Can now set hex label size relative to the current hex radius (4 size settings).

- Undo levels increased to 15.
