Changed the M_S instances to M_{SUSY} in RPC manual
Fixed SLHA2 output of neutral fermion mixing in RPV case
Added ridders method to numerics
Tweaked error messages for Ridders method
Added protection in 2x2 diagonalisation routines against negative
Merge branch 'master' into nmssm2
Add fillArray function also to DoubleMatrix.
Add helper function size() to DoubleVector and DoubleMatrix.
Generalize sPhysical::display(double*) function.
Now it works for arbitrary sized matrices and vectors.
Generalize nmsPhysical::display(double*) in the same way as
sPhysical::display(double*).  Now it should be easy for nmsPhysical to
reuse the code from sPhysical via sub-classing.
