* Use absolute error instead of relative error.
* Test on well-conditioned matrices.
* Do not repeat the same test g_repeat times (bug fix).
* Correct diagnostic output in matrix_exponential.cpp .

remove the hack to make the static assertion on types actually show up.

indeed, now that we use the meta selector for transposing as needed, the static asserts work very well.

Rewrote ei_handmade_aligned_realloc such that it is now using std::realloc.
Reorganized functions in Memory.h for better readability.
Add missing <cerrno> include to Core (it's now required in Memory.h).
