Small adjustment to a pv name.
Added getters and convenience functions to BioXASSideMonochromator for available pvs, converted all pvs to either AMReadOnlyPVControl or AMSinglePVControl (previously just AMProcessVariable). Many values are assumed--will need to check that the given conditions for convenience functions are valid.
Added getters for all controls in BioXASSideBeamline.
Sketch of super basic monochromator view, to be implemented in BioXASSidePersistentView.
