Slice already loaded PIL Image

[jasoriya]

Pull request for Issue #21

I decided to take input a PIL Image using the function slice_PIL_Image to maintain consistency. If anyone wants to pass a numpy array they can create a PIL image from the array. Do let me know your thoughts on the proposed changes.

Thanks Shreyans

@jasoriya You need to resolve the file conflicts first without backing out changes that have happened since you cloned. Even then its up to @samdobson to consider your changes.
