This header defines the Slice class template, which represents a view or subrange of a tensor without copying its data. It supports chained indexing, assignment, and comparison operations while preserving the underlying expression structure.

Key features:

• Zero-copy view into a tensor or tensor expression.
• Supports integer indexing and range slicing.
• Preserves shape, strides, and data type information.
• Works as part of the Tannic expression template framework.

Example usage:

Tensor X(float32, {2,2,2}); X.initialize(); 
X[0] = 1;    //arbitrary types assignment support.
X[1] = 2.f;
std::cout << X  << std::endl; // Tensor([[[1, 1], [1, 1]], 
                             //          [[2, 2], [2, 2]]] dtype=float32, shape=(2, 2, 2))
Tensor Y = X[1]; 
std::cout << Y << std::endl; // Tensor([[2, 2], 
                            //          [2, 2]] dtype=float32, shape=(2, 2))
std::cout << Y[0] << std::endl; // Tensor([2, 2] dtype=float32, shape=(2))
