Bug fix from this morning, adding distScore.coffee

I was trying to sort a dictionary, instead of a list. This produced an
error. Adding a file distScore.coffee
Scoring and sorting of bar charts

main.coffee - calc the scores
pairScore.coffee - scoring updates
distScore.coffee - added dist function for distinctiveness
charts.coffee - Changed it so that the object that will be passed to
main.coffee has the scores in it
main.html - displa dist score, this was put there mostly for
debug/seeing if that metric was useful
