#939

@NiklasGustafsson ,
The bins of numpy.histogram can use some preset formulas. I think it is also supported in TorchSharp, because tensorboard #936 will need it. What do you think?

I will use enum.

I like it a lot. Definitely use enums, we try to do that across the board. It's cleaner, statically typed, and sets up for Intellisense goodness in VS.

Do you have plan to check if it is possible to display what you have contributed e.g. Add torch. Histogram to polyglot notebook?

It will be tested with the tensorboard feature at that time
