/**
 * This class handles MyTracks related broadcast messages.
 *
 * One example of a broadcast message that this class is interested in,
 * is notification about the phone boot.  We may want to resume a previously
 * started tracking session if the phone crashed (hopefully not), or the user
 * decided to swap the battery or some external event occurred which forced
 * a phone reboot.
 *
 * This class simply delegates to {@link TrackRecordingService} to make a
 * decision whether to continue with the previous track (if any), or just
 * abandon it.
