Fixed a few tests in c4167f1 and 2c7c258

[orlandini]

Fixed cholesky for skyline symmetric matrix in 81b02c3

[orlandini]

Fixed cholesky for TPZSFMatrix in 89d36a1

[orlandini]

For the MKL bug, see: f7ea530

[orlandini]

MKL bug solved in 83f77db

[orlandini]

PR #103 made it clear that there is a bug in the HCurl approx space for prismatic elements

[orlandini]

Prismatic elements fixed in #122

[orlandini]

Closing #163 so we don't have redundant issues.
Test has comment NEEDS FIX
