Added tests to test methods in the Helper class.
Deleted unneeded comments.
Renamed the file that tests the adaline class.
Added the bias node.

I forgot to add the bias node into the adaline network. I added it and
now I am getting null pointer errors.
Partition data set delete comments

So that I don't have to try and log training with the entire data set,
I added a function that let's you partion a deta set into a smaller
training data set.
