Don't obfuscate classes with ProGuard; preserving names eases debugging.
Experimenting with Gremlin in extendo-android. Won't be possible at present, as Android does not support javax.script. Gremlin and its dependencies currently need to be included because of GremlinGroovyAnnotationHandler, used by FramedGraph, used by BrainGraph
Excluded gremlin-groovy from extendo-android, for good this time. Continuing to use Frames via FramedGraphFactory. This also avoids a ProGuard bug, allowing the optimizer to be used, keeping the APK small.
Make BrainGraph tolerant of missing Neo4j Lucene analyzer (currently the case in extendo-android)
