Building a neural network - again

You haven't created a neural network since the end of the first chapter, so this is a good time to build one (practice makes perfect). Build a class for a neural network which will be used to train on the MNIST dataset. The dataset contains images of shape (28, 28), so you should deduct the size of the input layer. For hidden layer use 200 units, while for output layer use 10 units (1 for each class). For activation function, use relu in a functional way (nn.Functional is already imported as F).

For context, the same net will be trained and used to make predictions in the next two exercises.

Define the class called Net which inherits from nn.Module.
In the __init__() method, define the parameters for the two fully connected layers.
In the .forward() method, do the forward step.
