This update includes several new features and bug fixes:
* Add the core ManagedObject class hierarchy for the new Pie API
* Add updated Boolean primitive implementation and test suite
* Add integration tests for symmetric key creation and registration
* Update demo and client logging to log at the INFO level by default
* Update README with improved testing instructions
* Fix bug causing enumerations to be encoded as signed integers
* Fix bug with mismatched EncodingOption tag
* Fix bug with relative path use for version number handling
* Fix bug with Integer primitive breaking on valid long integer values
This change adds a top-level version module to hold the version
definition for the library. This is then used in both kmip/__init__.py
and setup.py, allowing version inspection on import of the library and
automatic syncing of the version across the project.
