Restored the Automatic Build Test for models  {0,1,3}

Dynamic Modelling module "Process ROI as a single TAC" mode:  fixed interesting defect for all the models.  There was some undesirable "double->integer" conversion performed on the averaged ROI TAC.  So there was precision lost 0.5 units of signal on average.  Now fixed and is precise.

IN PROGRESS:   Verifying each individual Dynamic Model to work properly with the new Concentration Conversion mechanism.  Regenerating the ABT dataset

Upgraded APIs (application programming interface) to the Dynamic Experiment library so that  Callback functions for Signal->Concentration and Concentration->Signal are supplied for each model calculation.  This would allow each individual model perform fitting of the data in signal units instead of the concentration units.
