Updated the intersetion_num.java program to transcode the words in the manner we discussed on 11/18.

However, something still seems to be wrong -- the program is still returning intersection number for some words that xtrain says are pseudo-Anosov.

I also updated renamed some of the data files and gave them all consistent formatting.
I then updated the script insert_ints.py so that it can read through these (correctly formatted) files and calculate the intersection numbers.
added new data files with the self-intersection numbers in them.
