renamed all XxxRule to XxxConstraint (renamed tests accordingly), added annotation (SingleOutputResolution) to allow the specification of resolutions that will always result in a single value, implemented stub for warning when last resolution isn't a SingleOutputResolution to enable the user to review there written code
Merge branch 'master' of https://github.com/AHeise/sopremo-cleansing
implemented warnings if last resolution for a field can yield to multiple output values, name for constraints and resolutions are now defined by a @Name annotation at the class (previously defined in the register-functions in CleansFunctions-Class)
NonNullConstraint now has a @Name annotation
