Custom Sinks

You can create custom sinks, which can be passed to sink or sink! by defining two methods: SignalOperators.initsink and SignalOperators.sink_helper!. The first method is called when a call to sink is made (e.g. sink(MyCustomSink)). The second method is called inside sink! and provides the core operation to write blocks of frames to the sink. There is already a method of sink_helper! defined for AbstractArray objects, so you likely do not need to implement it if your custom sink is an AbtractArray.

You may also want to implement a constructor of the sink type that takes a single argument x of type SignalOperators.AbstractSignal. This should generally just call sink(x,CustomSink).
