TypingApi (client-server-api 0.9.0 API)

```
@Path("/_matrix/client/r0/rooms")
@Consumes("application/json")
@Produces("application/json")
public interface TypingApi
```
When a client receives an m.typing event, it MUST use the user ID list to REPLACE its knowledge of every user who is currently typing. The reason for this is that the server does not remember users who are not currently typing as that list gets big quickly. The client should mark as not typing any user ID who is not in that list.
It is recommended that clients store a boolean indicating whether the user is typing or not. Whilst this value is true a timer should fire periodically every N seconds to send a typing HTTP request. The value of N is recommended to be no more than 20-30 seconds. This request should be re-sent by the client to continue informing the server the user is still typing. As subsequent requests will replace older requests, a safety margin of 5 seconds before the expected timeout runs out is recommended. When the user stops typing, the state change of the boolean to false should trigger another HTTP request to inform the server that the user has stopped typing.
