Python data layer in prototxt

[Caleb Belth]

Can someone post an example of how to use the python data layer created here: https://github.com/BVLC/caffe/pull/3471 in a .prototxt model definition? Specifically, I want to replace the data layer in GoogLeNet https://github.com/BVLC/caffe/blob/master/models/bvlc_googlenet/train_val.prototxt with my own Python data layer.
