67f5379bea - Moved check on determinants in Woodbury kernels before inversion of B that was there by mistake. 
- Split SM2 into SM2 and SM2star so that keeps all updates for later when used in combination with the Woodbury kernels to improve the numerical accuracy to the same level as that of SM2.

837e160f17 - Added various Sherman-Morrison-Woodbury kernels 
- Separated debug information into 2 different debug levels.

22590b7684 * Woodburry 3x3 kernel fixed 
* Written Unified Sherman-Morrison-Woodbury kernel that partitions
  the updates in blocks of 3 and tries them with Woodbury 3x3.
  The remainder of 2 or one are attempted with Woodbury 2x2 and SM2.

For now the unified kernel gives fails where pure SM2 does not.
I suspect there is something going wrong in how the updates are partitioned.

f4becac4c0 First implementation of SM4 
SM4: Sherman Morrison, mix between SM3 + SM2
Leave zero denominators for later (SM3), and when none are left then split (SM2)

1d1da00931 Integration of vfc_ci 
The vfc_ci tool has been directly added to the repository, since it's
not integrated into Verificarlo yet. The vfc_test_h5.cpp file defines a
test inspired by test_h5.cpp that reads a list of cycles and dump the
vfc_probes for these cycles.

4bd61dd76c Add a standard Sherman-Morisson implementation 
- It can serve as a baseline reference

- It can serve as a starting point for including the pivot
  and splitting techniques from Maponi and Slaggel without the full
  complexity of the MaponiA3 algorithm
