overhaul into MEAN stack and framework-less backend
setting up angular modules - display
sass setup, sequence template, foundation overrides
Transport, pads service, pads controller, repeated button sets, pad directive with partial upload
transport tick handling, record pad press, pattern grid drawn with path playhead, record trigger schema and setup in pattern

pad and sample setup for timbre, no fx. sample editor modal setup with binds, no working fx yet.
trying async "parallel" loop through patterns for concurrent sample play
code style updates
bower update
Total pattern drawing refactor, transport planning for better clock

* draw pattern grid and playhead separately
* draw with native canvas methods because paper.js' overhead costs too many ms in processing between frames
* plan for better vinyl search methods and better audio scheduling using .start(s) and interval for
  scheduling sounds instead of an immediate, time-sensitive traverse on the vinyl

transport overhaul. making room for audio event scheduler. optimizing digests, css tweaks, some controller setup.
