Standardized File Names

[jordan-castelloe]

There are merge conflicts in this! I'll deal with them at the end!

Description

This PR changes a bunch of file names so they look like they were written by the Great Chicken Sloth in the Sky rather than a bunch of chicken sloths on the mortal plane.

Number of Fixes

Fixes issue #114 and #96

Expected Behavior

Naming conventions for file names:

Generates JSON

• Camelcase
• Plural with underscore
• /data/faker/products/_productsFaker.js

Route

• Camelcase
• Plural plus 'Router' /routes/products/productsRouter.js

Model

• PascalCase
• Plural /models/products/ProductsModel.js

Controller

• camelCase
• Plural /controllers/products/productsCtrl.js

Steps to Test Solution

1. npm data: generate shouldn't throw any errors (I redid the file names for faker generators)
2. npm start
3. Run gets on all the routes to make sure everything still works
4. /employees
5. /departments
6. /training-programs
7. /computers
8. /customers
9. /products
10. /orders
11. /payment-options
12. /product-types
