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 svn path=/trunk/externals/iem/iemmatrix/; revision=2947
