Do not allow the user to have access to these features unless everything has been setup properly.

Remove PeakOverlayFactoryBase class. Most of the logic had already been stripped out of this type. Also added a test for the NullPeaksPresenter since object of this type should be neutral in existance, yielding no noticable affect on the system whatsoever.

Fix issue where the correct slider to use is unknown.
Fix issue where the peakstransform is not getting updated with the new plot axis
Fix issue where the peak shape is fixed circular based on one axis range.
