Developer notes

I tried to make this plugin as un-intrusive as possible. Meaning it manipulates as little as possible of pre existing routes and database structure. Hopefully this will make it easier to maintain with future CTFd versions.

The only API endpoint which is overwritten with a custom plugin function is /chals (only returns challenges which meets its dependencies).

A wrapper function is also added to some other functions to prevent access to challenges with unmet dependencies. See the load function to find out which ones.

No pre existing database tables are manipulated. But a new table dependencies is added.
