Filter noise word in ex 6 3
Filter noise word in ex 6 3

I added code to filter out noise words. I found a list of noise words at
www.drupal.org/node/1202 and augmented it after running the program on a
couple documents. It's certainly not exhaustive. I ran into an error
about returning a pointer to a local variable. The right solution here
seemed to be making it a static variable to hold onto the memory over
multiple calls. I also had a good use case here for getting array size
using sizeof.
