Merge pull request #59 from backspaces/separate-files

Separate files: looks good, tried on all models and several test hacks of mine. Cool!
Cleanup for es6:
- Remove requestAnimFrame and Array.indexOf shims from util
- Remove "root" from util, use "window" in Model debug fcn
- Update animator to use "requestAnimationFrame"
- Atom: removed many trailing blanks
fix hopefully last reference to root variable!
Cleanup for wall following demo model.
- Fixed a few bugs relating to the patchAtHeadingAndDistance methods
- Added "left" and "right" NL methods
- Fixed trailing spaces via Atom's option to remove them
- Fixed the debug globals property
- Added colormap comments, getting ready for Color module
