Cursor hovering over the active layer with Real values now displays  "Real= ...value"

Implemented the ABT subtests for the DDC\Alpha model, new IVIM, IVIM-segmented models with the new parameters.

Implemented the ABT subtests for the DDC\Alpha model, new IVIM, IVIM-segmented models with the new parameters.

Added new Dynamic Model:  "DDC Stretched Exponential fit S = S0*(exp(-b*ADC)^alpha)"

Tested on the standard ABT dataset identical to ADC:

DDC fit:  DDC=0.0016, alpha=0.34, Residual=2.03

For comparison, we performed the ADC fit on the same data:

ADC fit:  ADC=0.001152, Residual=12
