Detailed Description

template<class F, class B>
struct WhereProxy< F, B >

The only legal use of where(a,b) is in an expression like:

A = where(f,B);

Rather than have where(f,B) return an array that could be combined in an expression, we return a WhereProxy that is recognized by assignment operators.

The WhereProxy is also necessary because the elements returned by where are MaskAssign<T> objects, so a special assignment operator, OpMask<Op> must be used.
