base class for function minimizers; user may give FCN or FCN with Gradient, Parameter starting values and initial Error guess (sigma) (or "step size"), or Parameter starting values and initial covariance matrix; covariance matrix is stored in Upper triangular packed storage format, e.g.

the Elements in the array are arranged like {a(0,0), a(0,1), a(1,1), a(0,2), a(1,2), a(2,2), ...}, the size is nrow*(nrow+1)/2 (see also MnUserCovariance.h);
