Start of hw4. Added parallel code from Josh to play with.

Ignoring all jpgs in the test/training catagories folder.
Editted parallel code to run on my machine
Problem 1 setup with feature extraction and random forest generation.

Parallel feature extraction. Only one feature extracted currently (im
size). The random forest is generated with 1000 trees. I test the
random forest classifier by looking at the confusion matrix. I have a
randomly prodiced test and training set. I'm playing with the canny
filter currently.
