.SS "template<class EOT> class eoNormalVecMutation< EOT >"
Simple normal mutation of a std::vector of real values. 

The stDev is fixed - but it is passed ans stored as a reference, to enable dynamic mutations (see eoOenFithMutation below).
.PP
As for the bounds, the values are here folded back into the bounds. The other possiblity would be to iterate until we fall inside the bounds - but this sometimes takes a long time!!!

.PP
(Default) Constructor. 
.PP
The bounds are initialized with the global object that says: no bounds.
.PP
\fBParameters:\fP
.RS 4
\fI_sigma\fP the range for uniform nutation 
.br
\fI_p_change\fP the probability to change a given coordinate

Constructor with bounds.

\fI_bounds\fP an \fBeoRealVectorBounds\fP that contains the bounds

for each component, the sigma is scaled to the range of the bound, if bounded
