This component roughly corresponds to "Client Room Send" and "Client Sync" on the WIRING diagram.
This component produces multiple binaries.
Internals
HTTP routing is done using gorilla/mux and the routing paths are in the routing package.
Writers
Each HTTP "write operation" (/createRoom, /rooms/$room_id/send/$type, etc) is contained entirely to a single file in the writers package.
This file contains the request and response struct definitions, as well as a Validate() bool function to validate incoming requests.
The entry point for each write operation is a stand-alone function as this makes testing easier. All dependencies should be injected into this function, including server keys/name, etc.
