Title: BTRSplitView

Because NSSplitView sucks. Come on, we all know it:

- Cringe-worthy delegate methods.
- An (almost intentional) aversion to animation.
- Positioning nightmares

BTRSplitView aims to solve the last two (if only because overriding delegate methods would be taking too much control into our own hands) with a subview drawing block, and methods to set and get the position of subviews easily, and in the case of setting, with animation.
