Adjusted the "slope" track so it would line up more perfectly with the ground, see #164
If the skater transitions from the right edge of the 2nd track directly to the ground then do not lose thermal energy during the transition, see #164
Made the Clear Thermal button have a regular cursor (arrow) instead of hand when disabled, closes #163
added assertions to ensure thermal energy remains non-negative, see #141
Fixed: thermal energy goes negative, see #141
Fixed location on track after two tracks are joined.  May also solve "flipping problem", see #150
updated version to 1.0.0-rc.6
removed commented-out code
Guard against negative total energy, which could occur of the user is dragging the track underground, see #166
If there is no potential energy (i.e. the skater is on the ground) then don't show the potential energy slice, see #165
Removed console.log statements, see #168
Fixed search space to use spline's parametric domain, see #169
Prevent the skater from flipping upside down when leaving the track, see #167
updated version to 1.0.0-rc.7
Fixed debugging statements, was crashing the app.
Made it so the track can't be dragged underground when dragged by the track itself (not control point), see #166
updated version to 1.0.0-rc.8
Merge branch 'master' into 1.0
