first implementation of the new elimitation algorithm
delay the replacement of Sign[Mu] to SignMu
Bugfix: make sure the solution for parameter n goes into the equation
for parameter n+1.
Bugfix: copy and paste error
add simplification rule to make the NMSSM EWSB eqs. solvable
generalize StripSign to catch more cases

In the NMSSM we have Times[Rational[-1,2], xyz] which did not match
Times[_Integer,_].
correct structure of the return type of ReduceSolution
remove debug printout
using TimeConstrained for each call of Solve
adapt the EWSB tests to the new structure
whitespace cleanup
Catch case where the solutions of one parameter cannot be related by a sign.
put note about new phases into the main routine
calculate the analytic solution to the EWSB eqs. only once
