Refine Multi-View Interface

[sourabhdesai]

Right now, the Multi-View interface for viewing the videos is pretty rough. It could use some UI touch-ups to make it more user-friendly. Ultimately, I've been going for a Google Hangouts look, with a large screen at the center and multiple tinier screens at the bottom. The tinier screens update their video frames in-sync with the playback of the large screen if the timing of the videos overlap.

Additionally, I think it's worth looking at an alternative interface where each video element is in its own panel that can be docked and shifted around the screen (in a sense, similar to the interface for Echo360). There are quite a few libraries that we can look into if we decide to go with this design. I'll list a few here:

• wcDocker
• DockSpawn
• GoldenLayout looks like the best to me but we'll have to look it's licensing info to see if we'd be able to safely use it for free.

Quick note, this issue should probably be under the ClassView repo (my bad). That is the repo that contains the code for the classview directive. Ill create a duplicate issue in that repo and link it to this one.
