2D forward-fitting projection code for fitting images of clusters of galaxies. This work builds upon the ideas in MBProj2.
This is in progress and is not yet suitable for serious use.

Usage notes:
-
If using a PSF model, I suggest fitting a larger region of the sky than necessary, but masking out the edges. Do not zero the exposure map in these regions. The PSF modelling uses a FFT convolution, so the model will wrap around at the edges.
-
Input images must have even numbers of pixels on each axis
