Majority of the code is borrowed from the Microsoft R Open Rprofile.site file.
In case MKL can be detected this information will be stored in a separate envrionment, which
other function know about. If so, an optimized version of function
will be used which used ordinary matrix-objects instead of matrices defined by the
Matrix-package. This seems to accelerate computation time for large datasets
by up to factor 30.
This function is for internal use only and therefore not exported.
variable 'MKL' in envir "msgEnv" will be set to TRUE/FALSE
