Split the pinch gesture into start,
change, and end/cancel. Each of those
are read in and then they emit through
the scope to functions in the controller.
Moved MCTPinch directive into
plot-reborn. Now emits on pinch action
the event to the controller. Edited plot.html
to clean up and edited mct-plot.html to
include mct-pinch. DrawLoader adjusted to
allow and prevent error.
