Added feature to observation creation
added prefix to feature name
Removed class name from Observation Model

NSInvalidArgumentException 'Unacceptable type of value for to-one relationship'
errors when internal core data code tried to create inverse relationship to subEntity of Observation
without the class defined, I can still use the class that was created, but now it doesn’t do checking
Yeah! I can now create a feature with the new protocol file
Fixed ability to load saved features
minor misc. cleanup
Implemented multi-feature symbology in protocol
drew mission observations/mission properties
