Hook into database and create seeder data

[spjy]

I'd like to start connecting the views with the API so we have real data to work off of.

@mrbarbasa recommended that we use Knex or Bookshelf as an ORM to connect to our PostgreSQL database with the API.

In addition to hooking into the database, create some rows in the database of some of the plants we plan on training with.

Tasks:

• [x] Hook into the database with an ORM
• [x] Create a database schema -- can just use Knex
• [x] Create seeder data of plants we will be training off of
