This version makes sense only for two phase level set function. In the multi phase case any object phase is changed to the background, while a background pixel/voxel is changed to the first object phase.

public MTBGenericEnergyNonPDE init(MTBImage img, MTBLevelsetMembership phi)
MTBGenericEnergyNonPDE
This method assumes, that all class parameters of the energy are already set and takes care of initializations which depend on the image to be segmented and/or the initial level set function supplied as argument. It may also be the case that depending on the image and/or the initial level set function a new energy object is created, e.g. if a specialized energy according to dimensionality of the image of the type of the level set function (multi phase) is required.
If no initialization is required the routine should just return the unmodified energy object.
