 * promote.h   Arithmetic type promotion trait class

 *
 * This trait class provides a mechanism for type promotion on vectors,
 * matrices, and arrays.  For example, when you add a Vector<int> to
 * a Vector<double>, the result should be promoted to a Vector<double>.
 *
 * Sample usage:
 * template<class A, class B>
 * Vector<promote_trait<A,B>::T_promote> operator+(const Vector<A>&,
 *      const Vector<B>&);
