first stab at traceur
remove use stricts -- traceur assumes strict mode
convert to classes
remove old extends imports
remove bind(), use arrows instead
better organize directives and services
better structure the patch rendering
more directory structure
more moving things around
ng-cloak the page so elements dont show up half-rendered;
fix elevation layer bug
introducing transfer function menu
pulling "transfer functions" out from underneath models
remove transfer function stuff from ModelPool
fix bug
break main controller into mixins
loading screen with app fadein
have the splash screen hide itself
add evented class, handle model update callbacks through it
faster way to set imageData in elevation sampler
