Revert "removed bingtest.py from directory"

This reverts commit 89921bef8cd027a917f22c30cb7d39b32448ce29.
corrected termscore tally, search terminates with 10 nonrelevant docs
Merge branch 'backToDescription'
We have decided to take terms from the description because clic does not support nltk
Decided to go back to description as term source.  feedback loop stops after search returns all nonrelevant documents
copy and paste error, works now
