Hey @zanussbaum, 

Regarding on how to proceed with the implementation, could you maybe post your questions here and tag @patil-suraj and @patrickvonplaten so that we can move forward? :-)

Hey @patrickvonplaten, I actually chatted with Suraj this morning and
cleared my questions up about the Self Attention Module. I am working on
implementing it and hope to have something out this weekend!
