Add documentation of each week

[emsesc]

The Javascript camp documentation does not include week descriptions. In the root directory and in individual week folders add:

• A "summary" section (refer to Serverless) that provides gifs where applicable that demonstrate the deliverable of that week.
• Learning objectives that concretely establish what students should take away from that week

In each individual week folder README.md files, also add:

• A section that explains how the livestream helps students with homework. This should clarify for contributors how the two portions of the bitcamp work together.
• Short and concise description of the live stream and homework
