TrigNavTools: Implemented roi, features
Three essential improvements in the graph:
- correct roi connection with propagation through the graph
- feature elements added also with the multi-H node cases
- node compression algorithm excludes "absent" features from the hash calculation
- fixed problem with track collections
- featrures with SG key==0 removed
- many tests done (they are options commented in .py script)
