Method is_contiguous

* @brief Checks whether the tensors in the list are packed sequentially, without gaps. * * The function checks if the data pointer to a next sample immediately follows the last * element of the previous sample. There's no constraint on the shapes of the samples, however. * To determine whether the tensor list can be reduced to a tensor, see @ref is_tensor. */
