You're on the right track.  You won't be able to do too much about the 
constructors, but the operator= is an easy fix:

class Tensor : public Array<double,3> {
public:
  Tensor(int d1, int d2, int d3) : 
Array<Double,3>::Array<double,3>(d1,d2,d3,fortranArray) {}
  ~Tensor() {}
/* NEW */
  using Array<double,3>::operator=;
}

C++ allows inheritance of operator= via that syntax, it just doesn't do 
so by default.
