I tried running fizzy.py and got the following error:

```
$ fizzy.py -i data.biom -m map.txt -c Class -o result.txt -f JMI -k 15
Traceback (most recent call last):
  File "/home/jrideout/.virtualenvs/qiime-fizzy/qiime/scripts/fizzy.py", line 94, in <module>
    main()
  File "/home/jrideout/.virtualenvs/qiime-fizzy/qiime/scripts/fizzy.py", line 81, in main
    open(opts.input_path,'U'), 
AttributeError: Values instance has no attribute 'input_path'
```

This is related to the option renaming.
