Monitor execution graph #2
Description
Add a support to display the execution graph, similar to tensorflow.
The graph should be generated by the user manually (since it requires data). Something like monitor.push_graph(sample).
The monitor should provide:
- an interactive graph with information about in input-dim, output-dim, module dim at each node
- named-scope, similar to tensorflow. Allow the user to define custom names and groups of the graph (check if there is a easy and clean way to do it)
- save the graph image
