CTPy-15 Identification of raw data samples to classifications:
Added experiment tracking - record completion - after classification identification for all classifications.
Basic infrastructure for a parallel version of classification identification.
CTPy-16 Parallelize classification processing
CTPy-17 Configuration option with json files, overriding core init.py

created CTPyConfiguration class, which has the old defaults from __init__.py, deprecated and removed the latter, made all scripts which need those constants use the configuration file.  Everything seems to work, need a bit of testing.
