Droping down CMake requirement
First commit of Mara using git.
Small adjustments to make mpi, fftw and hdf5 compile correctly.
Added plots back into 1dtest.lua.
Updated visual module draws textures from lunum arrays.
Small changes to vis.
Visual routines are gone from the master branch.
Removed vis.hpp from src directory.
Have 2d texture drawing working correctly.
Added a Mara function to get colormap data from image.c, also changed Mara_write_ppm to Mara_image_write_ppm.
Merge branch 'lua_glfw'

Conflicts:
	src/Makefile
	src/lua_vis.c
Noticed that lua_vis_load was not void, like its prototype in luaU.h.
Noticed that #defines did not account for FFTW but no MPI in lua_fft.
First possible successful mpi sampling code.
Moved Lua code out of sampling.cpp, the call is made from mara.cpp now. sampling.lua test performs correctly on 10,000 points x 16 mpi procs on laptop.
Modififed subgrids.cpp SubgridAtPosition not to iterate over non-existent dimensions.
Generalized sampling to work in 1,2, or 3 dimensions. Mildly tested in 3, nothing else yet.
