CSKDeltaQueue	Signal K delta queue
CSKEmitter	A class that produces Signal K output to be forwarded to the Signal K server (if the system is connected to one). Signal K is reported via the as_signalK() method
CSKListener	An Obervable class that listens for Signal K stream deltas and notifies any observers of value changes. This serves as a base class for code that needs to listen to the stream, with the most common descendant being SKValueListener
CSKMetadata	Holds Signal K meta data that is associated with the sk_path an SKEmitter class may optionally send to the server. According to the official Signal K specification: "All keys in the Signal K specification must have a <tt>description</tt>, and where the key is a numeric value it must have <tt>units</tt>". Thus, any paths that you output that are not already part of the official Signal K specification should have these two fields defined as metadata
