Need the ability to create a new customer

[ryanjcohen]

As a user I need the ability to register my information as a customer and create an account So that I can create wishlists, receive recommendations, place orders, and more on the eCommerce site.

Details & Assumptions:

• Endpoint: POST http://[Our API address]/customers
• Expected JSON request body format

  {
  first_name: "John",  
  last_name: "Smith",  
  user_name: "XXX",  
  addresses: ["123 Main St, Buffalo, NY", "50 John Stree, NY"]  
  password: "XXX"  
  }

Acceptance Criteria:

Given a valid JSON request body specifying a new customer's information
When I submit the create customer request by calling 'POST /customers' 
Then I should receive an HTTP return code of 201 and a JSON object representing the newly-created customer

Added Acceptance Criteria

Just making small change to acceptance criteria to make the JSON body formatted as a code block

Ranking as 8 for now, as we might end up doing more error-checking/validation on the request for this endpoint than for some other endpoints (ex. GET endpoints)

Should duplicated username should return 400?
