Merge pull request #37 from bennlich/tfunc-es6

Updated transfer functions, removed autofill/clear veg buttons
take $scope dep out of TransferFunctions; untabify TransferFunction
adding some missing imports; introducing some array comprehensions
more jshint cleanup
break Util out
move docs-only file into docs
pull gradient into Util
rm old stuff
separate a generic api from the core app; generic api still needs cleanup like removing angular $scope dependencies
move "sub-apps" into their own dirs
remove angular deps from generic code; broke sensors though;
get sensors to work again
add some comments
make sure the mixins are initialized after the map/elevationServer. when using the vegetation transfer functions, implicitly turn on the vegetation layer.
