* bug fixes in: Dot, generalized eigen problem, singular matrix detetection in Cholesky
* fix all numerical instabilies in the unit tests, now all tests can be run 2000 times with almost zero failures.

# CMAKE_GSL_CXX_FLAGS = Unix compiler flags for GSL, essentially "`gsl-config --cxxflags`"

# GSL_INCLUDE_DIR = where to find headers
