Detailed documentation of mx.symbol.contrib.MultiProposal

I cannot find any detailed documentation of MultiProposal. Implementation itself would be helpful. (First of all, I want to check the dimensions of input and output)

Multiproposal follows exactly the same functionality of Proposal op, but supports batch size > 1. You can checkout Proposal op if that helps.

I checked it, but I think that helps little. Anyway thank you for your advice.
