Create validators for the /scheduler endpoint.

[ryanhallock]

Issue Currently, anyone is allowed to post any schedule they want. These schedules might not be correlated to the correct period. #147 is an issue that is tracking, an issue that would have been solved if we had it.

Feature Request We need a validator to see if the period correlates with their requested schedule.

Other conflicts

• 147 - ensure the request is sent correctly/update on changes

Plausable Solutions

• Create a validator to ensure that the sent sectionID, correlates with the period.
• Change the endpoint only to use the courseID and the period to ensure the correct sectionID placement inside the database.
