cmake Finds: improve the way library dirs are added in blas/lapack, remove blas lib to search in essl

The adaptive algorithm have been updated to use them.

Add a peek method to check timer without stopping it
Make tac return elapsed time
Add c++11 std::chrono timing

The methods `name` and `description` are implemented.

The timers are mapped to a std::string. The basic ones (P2L, P2M, M2M,
M2P, M2L, L2L, L2P, P2P) have a constexpr definition. Any new timer can
be added by calling `Timers["timer name"];`.

avoid to look into default system path automatically to find blas/lapack, we handle it precisely with HINTS keyword to use these paths only when necessary
