1) bug fixes: non-initialized ide_strength when no param is  identified; normaliz1 set to one when prior std is inf; HIGHEST SVD bar fixed (wrong singluar values were plotted).
2) Simplified advanced output (no more multicollinearity and pair-wise correlations!).
3) Beautified output of collinear groups of variables.
4) use of sensitivities normalized with std errors.
