Snap companion dapps are not thoroughly documented. This issue is to clarify what they are, when they're needed, and how to restrict access to them using RPC allowed origins. Providing some examples of companion dapps would be useful.

Also should include how to auto-connect with initialConnections which isn't documented at all yet :(
