Nathan Berger 37967bd0cf Fixed case where function didn't return where it should 
I added these return statements so that invalid inputs or valid end cases would no longer continue running through the rest of the function.

Nathan Berger 8fb1eb7bdf Implementation of a regression tree in python 
I've implemented a basic decision tree in python as an example of how they work. Although the class I've created only works on one dimensional data sets, the reader should be able to generalize it to higher dimensions should they need to.
