------------------------
Added support for int8, int16, int64 and float32 column types. Also added basic
tests for all column types (requires ``nosetests``).
To run the tests, first obtain ``nosetests``::
$ pip install nose
Then, to test::
$ nosetests
Issues Resolved
...............
Fixed issue with ObjectIDs containing NULL bytes. (ObjectIDs now use a 12-byte
'void' array type in numeric Python.)
