Redesigned to recalculated viewable data points as needed using recalculateData(). This should be done, but should be thoroughly tested still. Removed Amplitude Tare button and added Tare Index text box (and all of its lovely rules). Tweaked getReferenceAverage() to now use amplitude-adjusted reference average. Anchored new controls. Reference sensor check boxes are now independent of everything and behave like every other check box. Still need to tweak behavior of everything with the taring controls.
