Functional: 
	The declensions setup screen
	The new declension data model
	saving declensions by dimensions per word
	enforcing mandatory declensions
	saving declensions to file
	translating old file formate into new
Partially Functional
	the lexicon's declension screen (still needs deprecated declension functionality)
	reading new file format (still needs to read 0.7.5 format and TESTING)
Nonfunctional:
