Bugfix: We can make the eigenvalues positive only in case of complex
mixing matrices.  Otherwise we have to keep negative eigenvalues.
Before calculating the spectrum, run to the susy scale.  This prevents
tachyons in the MSSM, because calculating the spectrum at the MZ scale
often yields tachyonic Mhh.
Put the testing of the MSSM high-scale constraint into a separate
test program.
Do not create own high-scale constraint within the initial guesser.
Instead, take it from the outside.
take the first scale guesses from the constaints
add model name to the list of global rules
Make the model name a global replacement rule to simplify the function
calls.
Add time stamp to each generated file.
