These are now implement in the FTMachine base class.

These can't be left here since now the design depends on getting the correct version called due to static type casting of FTM pointer and not on inheretance and and specialization via overloading.

Make a sensitivity image (sensitivityImage), given the gridded weights (wtImage).

These are related to each other by a Fourier transform and normalization by the sum-of-weights (sumWt) and normalization by the product of the 2D FFT size along each axis.
