BPnd (6 Calc. Methods): Calculation of BPnd with all 6 Reference Methods

As a facility for the user the BPnd (6 Calc. Methods) "model" has been implemented which calculates BPnd using all the reference methods described above in a single processing. If the system has more than N CPUs or cores (N>2), the processing is running on N-1 CPUs in parallel.

This model allows fitting k₂' which is used in the SRTM2 and MRTM2 reference methods using the SRTM method. Otherwise, a k₂' has to be manually entered. It also allows fitting t* using the Logan reference plot based on the k₂' determined beforehand.

The actual pixel-wise calculation is performed by the individual PXMOD models described above.
