Sends an event for the very first and last data samples as well as any time any of the plug-in's defined channels transition.
Configuration Options provided by the pre-processor :
NONE. The plug-in takes full responsibility for specifying all needed parameters/options.
Every event is a RAW DATA event. The data parameter contains a snap-shot of the data channels at the timestamp. Your plug-in uses the masks returned from channel-select objects to extract the pieces of data you are interested in.
