wish i could sleep.  more work on sentiment

sentiment analysis work.  stanford NLP stuff refuses to recognize the
englishPCFG.ser.gz library despite lots of fussing with it.

Two options are proposed here.
- One is using DatumBox and Python (easily ported to Java if needed)
- The other is AlchemyAPI, a paid service limited to 1,000 requests/day.
This may not be as big of an issue as we think.
