Aleksei, this looks very good, just a few things and we can get going:

1. Please rename CrfBasedNer to CrfBasedNerApproach to match other annotators name standard
2. Please update AnnotatorBuilder.getCrfBasedNerModel with using datasetPath even with an invented source to make sure we are testing it, so it is used by CrfBasedNerPipelineSpec
3. Optional but suggested, handle invalid path or read from jvm resources (perhaps use the ResourceHelper Resource class)

Thanks

This is work in progress, not yet finished for review

I've renamed and added dataset to tests.
Got stuck a bit because Annotation Result refactoring left small problems and bugs in .ipynb code.
