discussion screen ui, presenter, view added

[mdrahil]

Fixes #103

Description

I have implemented the Discussion Screen UI, added Presenter and View also. For now, on clicking home screen quiz items it will navigate to the Help/ Discussion Screen. The discussion screen has only dummy items for now. Once the "load comments and add comment" API will be available from the data layer there are some todo items those need to be implemented. For now please focus on UI only.

@mdrahil this looks great. You have not only implemented the UI but you have followed the current design and created presenter. Awesome work. Even if we select someone else's UI, we will use the presenter and adapter in this PR. Thanks for your contribution.
