Args:
domain: the domain to create the wavelet on. This should

wavelet. (wavelet.domain). Exceptions are situations
where the robot is calling new_wave outside of an
event or when the server is handling multiple domains.
participants: initial participants on the wave. The robot

message: a string that will be passed back to the robot
when the WAVELET_CREATOR event is fired. This is a
lightweight way to pass around state.
