Title: added sample_count_by_category

Was handy for a study I'm working on. Just wanted a quick method to see how many samples were associated with a particular category value. Below is an example of the output. I didn't see anything comparable already, but I could be mistaken.

$ ./sample_count_by_category.py -i ../examples/qiime_tutorial/Fasting_Map.txt -c Treatment
Control	5
Fast	4
