-) removed obsolete commented lines or unused variables;
-) when Asymptotic Hessian is available, take SVD of that for identification patterns;
-) when computing analytic  Hessian, scores are not necessary (no_DLIK=1);
-) fixes in output info when Hessian is available.

-) cosmetic fix to header

* 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.

Fixed bug in remote parallel execution introduced by previous commit b7133ebe

under parallel execution do not do parallel plots when some slave is octave, irrespective to master being matlab.
