/// Generate DTrackCandiate objects based on the generated particles.
/// This uses "truth" information (information that won't be available
/// in read data) to make a list of more or less perfect track candidates.
/// Because tracks can multiple scatter or even hadronically scatter in
/// the target, the generated value may not always be correct. However,
/// on average, it is going to be very accurate.

/// This is used for debugging purposes in the tracking code and is not
/// normally used otherwise.
