1269392822 Created the IndexPair type to store pair of tensor indices. CUDA doesn't support std::pair so we can't use them when targeting GPUs. 
Improved the performance on tensor contractions

f50548e86a Added missing tensor copy constructors. As a result it is now possible to declare and initialize a tensor on the same line, as in: 
Tensor<bla> T = A + B;  or
  Tensor<bla> T(A.reshape(new_shape));
