[Insight-developers] OnePlusOneEvolutionaryOptimizer

[Brad King]

Jisung,

The OnePlusOneEvolutionaryOptimizer is the only optimizer that has a
template argument.  It looks like the argument can be removed in favor of
a run-time pluggable value.  For example, the
FastRandomUnitNormalVariateGenerator does enough work in
GetNormalVariate() that a virtual dispatch to the method wouldn't hurt
performance.

I suggest that the optimizer have a SetVariateGenerator() method that
takes a pointer to a NormalRandomVariateGenerator class with a virtual
GetNormalVariate() method.  This change would be consistent with the other
optimizers.
