Given the sky image (Fourier transform of the visibilities), sum of weights and the sensitivity image, this method replaces the skyImage with the normalized image of the sky.

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.

Required since MultiTermFTM needs vectorized version. And this is implemented in FTMachine (the baseclass).
