Improved version.
...
- All static arrays replaced by dynamic ones
- All overhead induced by checking before and after running of the kernels replaced as much as possible with calls to MKL/DGEMMs.
- Solved bugs due to dimension mismatches.
Overhead time is dramatically reduced because no more calls to naive 'matmul'.

cuBLAS version of Woodbury KxK is working, but called to lapacke dgetrf/ri need to be replaced with cuSOLVER calls to eliminate intermediate results to be transfered to/from device.
