Spike/Research: Workflow of timesheet submissions and notifications

[izzyconner]

As a developer, I need a system in place to forward timesheets along the workflow of approvals and notify the necessary employers and administrators.

Workflow is as follows:

1. Employee fills in and submits timesheet
2. Employer looks over timesheet - leaves comments if necessary, send back to student if changes are needed, otherwise approve ticket
3. Once employer has approved timesheet for given time period, notify approver and open timesheet for final approval and comments from them.

This needs to be taken into account in the implementation of timesheet POST endpoints and design of the timesheet schema.

To complete this ticket:

• Diagram out the schema needed for notifications
• Research and write-up the tools needed for sending emails/other notifications to users

This ticket is necessary to complete implementation
