Number of product units in a region graph per layer

[chandan21gupta]

Hello All First of all, nice work with the framework. This is an extremely useful package for modelling region graphs and gradient based learning, which (correct me if I am wrong) I haven't yet found in any other library. Kudos to the developers.

There is one thing issue (or rather doubt) that I would like to discuss.

In region based graphs, while in the library itself, there is an option to specify the number of sum nodes in each layer. Why isn't there an option to define number of product nodes also in the decomposition? Also, it will be great if you can also attach some references for region graph based on which the API works.
