Detailed Description

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.
