Feature/template crud

Description

Covalent-Data's mock object creation and schema parsing has been updated using the very powerful Go template libraries. This allows for several things:

• actionable functions within schema
• embed different schema into a top level schema
• manipulate datum before outputting to mock objects

What's included?

• New example for users
• New gitbook based documentation (still a work in progress)
• Heroku deployment dependencies added

Test Steps

• peruse /schemas/users.yaml and /schemas/address.yaml to see how they are formatted
• install Docker Engine
• in this directory, docker build -t covalent-data .
• docker run -p 8080:8080 --name covalent-data covalent-data (docker stop covalent-data; docker rm covalent-data to stop and remove the container)
• GET to http://localhost:8080/users
• select a user, copy their database_id, and look them up (GET to http://localhost:8080/users/{database_id})

You should see a new users schema, with the embedded mailing_address schema in the returned JSON.

Tested and all current functions look good to me!
