+ * 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
