Split base class CellularPanel out of TrackPanel...
... To be reused with the Ruler too. The new base class does all the handling of hit tests on cells and managing of UIHandles, and keyboard events and focus. It has no knowledge of tracks -- that all resides in overriding functions in TrackPanel. Still to do, of course, is reorganizing drawing with callbacks to the cell objects.
