WIP: Begin setting up API endpoints - will close Issues #3, #7

[letakeane]

Began editing the src folder:

• controller
• router

Currently researching:

• how to create endpoints for accessing the app's backend
• how to pass data from the components (such as ImageCapture) to the controller

[letakeane]

Second commit on this branch will add a dotenv file to obscure the API key

NOTE: No longer using backend to store images
