removed accidentally added submodule
Switched out #pragma once for old style header guard
Adds many functions for testing purposes. Makes some functions of r^2 rather than r which is making it not work for some reason
Removes some of the utility functions from the top of the invmed.cpp file and moves them to invmed_utils.hpp. Declaration and definition included in header (for simplicity). Adds option for full or only partial observations (a bit of a hack, needs to be improved).
Completely redone. Adds more tests.
