pgmpy `DAG.to_pdag()` not implemented

Currently DAG.to_pdag() is stub that always returns None. This could confuse users. It would probably be best to leave the method out completely until it has been implemented.

The dagitty package provides this functionality with equivalenceClass() (doc, pp. 13 - 14). The code that implements this is the JavaScript function GraphTransformer.dagToCpdag() (code, lines 1167 - 1184) with unit tests (code, lines 64 - 69).

@behrman Thanks for reporting this. I will remove the method for now till it is implemented.

@ankurankan If you can remember, please comment to this thread when DAG.to_pdag()has been implemented. I will update the pgmpy tutorial I've written to include an illustration of its use.

Can I contribute in making of the function DAG.to_pdag() ?
