Reuse local variable instead of hard-coding the MX scale guess.
Use better initial MX guess to prevent the default E6SSM parameter
point from failing.
Remove depenendcy of Mssm_parameter_point on lowe.h.
Add verbose debug output: print current accuracy (and accuracy goal)
Initialize variables in the order they are declared.
Set uninitialized parameters in the E6SSM.  This solves the convergence
problem.
Better guess for the NMSSM GUT scale.
Adapt the coupling monitor to Eigen::ArrayXd
Long debug output only if verbose mode is enabled
cleanup whitespace
Add wrapper functions for the absolute value
Bugfix: Properly decompose the output variable into phase times
absolute value (not squared abs).
