Finally committing something that I've decided I want to keep.  I've been writing and deleting code for a few hours now trying to get energy views to not jitter and use global coordinates.  But now I think I'm going to go back to my idea of giving the chunks relative coordinates in the model
Fixed a bug in RectangularThermalMovableElement that caused the slice bounds to be generated incorrectly and a filled in missing mass and specific heat for the beaker
Slices are translated with the element so EnergyChunkDistributor.updatePositions function can (hopefully) work correctly
Added a masking layer for the beaker's energy chunks and temporarily made the beaker's energy chunk distribution loop shorter because I think it's broken.
