Remove unused subroutines, make internally used subroutines private (prefixed with '_')
Removed unneeded Java import
Removed unused Java variable
Fixed Java code: formatting (indenting, spaces instead of tabs, etc.), renamed class and methods
Moved "GephiLayout" Java project from "java/" to "java/GephiLayout/" in order to make space for other Java projects
Moved CRF model runner Java code to a Maven-based (usable with NetBeans) project because it's faster+easier to develop, test and debug Java code that way
Made the CRF "ModelRunner" Java class non-static in order to 1) isolate implementation details from Perl code, and 2) make the memory usage more isolated
Got rid of SimpleTagger.apply() to make the implementation fully non-static
Removed unused import
Removed verbose memory usage output
Merge branch 'inline_java_optimization' into optimize_extractor
