Public actions

join a room by emitting a "join" event with payload
```
{
    id: "optional room id",
    username: "my screen name"
}
```
- If no id is sent a new room will be created with a randomly generated unique id
- creating a room automatically sets the creator as the room owner. Room owners cannot be changed. To 'change' an owner just create a new room
To send your estimate to the server emit a "set_estimate" event with payload
```
"estimate as string"
```

Valid estimates include, although not limited to, 1, 2, 3, 5, 8, 13, 21, "", ?, pass, ∞, ¯\_(ツ)_/¯

IMPORTANT NOTE:
Estimate values will be masked with "X" until the cards are flipped

as the owner you may flip the cards by emitting "flip_cards"
- this will return the state the current state of the room and expose the values selected by participants.
- once cards are flipped participants will no longer be able to change estimates
as the owner you may reset the game room by emitting "reset_cards"
- all estimates will be reset and flipped status will revert to false
