PyTorch nn Layers entry

[DigitalDruid10010110]

Description

This PR includes the completed draft of the 'Layers' documentation. The document provides an explanation of layers in PyTorch, syntax examples using nn.Sequential(), and a simple multi-layer model. My motivation for this project comes from my portfolio project for "Learn Git & GitHub" course on Codecademy.

This was a difficult project for me as I had no previous experience in machine learning or PyTorch let alone knowledge of layers. The process of learning and taking the courses to learn enough to create this document was really rewarding and helped break down some walls of fear and anxiety. I look forward to your review and any suggestions you have.
