StarCluster Implementation Status descriptions

Status	Description
Not Implemented	The Keyword is defined, but no further processing is done. Alternatively, the HDU type is not recognised.
Basic Implementation	The Keyword is defined within he structure of the FITS file and structural integrity is validated. Data is not loaded.
Processing implementation	Initial actions are implemented and properties are created.
Post-processing implemented	Triggers and validators are called and data is reflected on corresponding Astro objects.
Complete implemented	The Keyword parsing is fully implemented, astronomically meaningful information (if any) is extracted, but not fully tested.
Tested implementation	All aspects of the Keyword record are fully tested.
Blogged	Blogpost and documentation describe the Keyword record.
Deprecated	The Keyword is deprecated, or there is no need to be handled by the software, so it is ignored. The format is checked for correctness. Some deprecated Keywords must be parsed for compatibility reasons (e.g. EPOCH).
