K-trans dynamic modelling:  fixing a defect, model calculation is not performing as expected.
Testing on a sample prostate DCE volume.

Defect was due to the change of time convention in FireVoxel. From a certain Build, the Volumetric entity contains the absolute time in seconds, however some models require the starting time be "0".

This seems to resolve the issue.  Also added a new feature for this model - comparing the data curve to modelling curve. 

 We also are able to generate voxel-wise maps properly. See a screenshot below. This is the K-trans map

PET project:   Was able to incorporate timing information for all frames. For this non-gated acquisition the following logic was used:
(Frame Reference Time (0x00541300)+Actual Frame Duration (0x00181242))/2


Now Dynamic PET datasets can be loaded, ROIs can be constructed and corresponding TACs (time activity curves) can be obtained.

3 ROIs and corresponding TACs
