Module
Module is the abstract base class for every layer, activation, loss, and container in GradCore-Tensor. If you want to write a custom layer, you subclass Module. If you want to understand how a layer works internally, you understand Module first.
Sequential
Sequential is a Module that holds an ordered list of child modules and runs them one after another during forward(). The output of layer N is fed directly as input to layer N+1. That's it. Simple, composable, and the backbone of every model in GradCore-Tensor.
