Base class defining the methods that a LensFitnessObject can use to calculate the fitness of a specific lens.
Two implementations currently exist. The first, and simplest, is the ImagesBackProjector class. It takes a GravitationalLens object (like a lens model created with GRALESHELL using for example 'lens/new/mplummers') and a list of images data and calculates a number of properties (backprojected image points, convergence, shear, ...) and stores others (measured shear for example). It is this implementation that is used by the GRALESHELL command 'imgdata/fitness'.
The second implementation, BackProjectMatrixNew, is somewhat more advanced, but is only meant to be used inside the genetic algorithm. It is more advanced in the sense that it used information provided by the LensFitnessObject to make sure that the calculations are done in an efficient way, only calculating those things that are necessary. This also means that your program will crash if you try to access information that the BackProjectMatrixNew instance believed was not necessary to calculate.
