Adding a few functionalities, the biggest being the ability to splice the potential field instead of only the density field. Added an additional minimization technique (MINRES) which appears to be much faster than CG for both splicing types. To perform potential splicing, one should comment out the -DZELDOVICH_GRADIENT_FOURIER_SPACE flag in the Makefile, and enable MINRES (in the param file using set_minimization MINRES).
