split the objects from mtx_binops into several files: mtx_add, mtx_sub, mtx_mul, mtx_pow
mtx_binops is still there for glue functions
exposed some important operations on float-arrays via iemmatrix.h (mtx_doInvert, mtx_doTranspose, mtx_doMultiply)
as you can easily see, they all start with "mtx_do" and a capital letter;
they all return a pointer to (newly allocated) memory with the result
