fixed constraint value ranges
started to refactor flipping constraint definition using new approach
added new motion templates needed for flipping action
minor change in exec trace query predicate
updated set of available constraint classes to new left/right/above/below structure
pancake motion definition using inherited motion templates. Leaving it like this for now, have to test execution and possibly integrate with expression graph
corrected feature type: perpendicularity needs a directional feature
cleaned loading of OWL files
added feature_properties description for point features; uses zero vector if position not given (i.e. if all positions are relative to the object center, this will denote the object center itself)
introduced named class for pancakemix restriction to make clearer that all three motions basically share the same tool
knowrob-openprs db interface developed for saphari 2nd year demo committed
Merge branch 'master' of https://github.com/knowrob/knowrob_addons
tiny change for the compatibility with the latest CRAM logs
added properties and classes for new CRAM log structures
copied tfjava files to tfmemory since more substantial changes are needed for proper reasoning about logged transforms
added lastAccessed field storing the time stamp when stored transform has been accessed the last time
simple garbage collector based on lastAccessed field instead of age w.r.t. current time
adapted tf memory to new garbage collection scheme -- reasoning over time works now also with multiple time slices after each other
removed duplicate class file
Made changes at the java side since  uima_uima_results table does not exist anymore.
