Test objects returns/json

[ezavesky]

Adapting from pull #45, output list of JSON objects in results to FILE not stdout.

• Merge most recent master changes into branch.
• Slight rework of reporting logic so that JSON results will come back if run in multi-process mode instead of just single core version.
• Updated profile scripts to give example usage.

added useful compute for timing offset to JSON return as standard, not verbosity mode; bump test script to profile against extra search time computation
