This server allow to relay bidirectional JsonRPC messages between clients
connected to it. The protocol use a extension of the standard JsonRPC 2.0 with
the addition of a to field to indicate the identifier of the destination
client. This makes it transparent to the parameters given to the calls. It also
provides support to send messages in broadcast by setting null as its value.
This module export a function that when called will generate a handler function
for the connection event of the WebSocket server objects created with the
ws module.
Internally, connections are registered so incoming data can be send to the
corresponding destination. Destination is identified with a to field, besides
that data are plain JsonRPC messages.
