* js_channel is a very lightweight abstraction on top of
* postMessage which defines message formats and semantics
* to support interactions more rich than just message passing
* js_channel supports:
* + query/response - traditional rpc
* + query/update/response - incremental async return of results
* to a query
* + notifications - fire and forget
* + error handling
*
* js_channel is based heavily on json-rpc, but is focused at the
* problem of inter-iframe RPC.
*
* Message types:
* There are 5 types of messages that can flow over this channel,
* and you may determine what type of message an object is by
* examining its parameters:
* 1. Requests
* + integer id
* + string method
* + (optional) any params
* 2. Callback Invocations (or just "Callbacks")
* + integer id
* + string callback
* + (optional) params
* 3. Error Responses (or just "Errors)
* + integer id
* + string error
* + (optional) string message
* 4. Responses
* + integer id
* + (optional) any result
* 5. Notifications
* + string method
* + (optional) any params
