/*
 * Author: Lambda.Tiger
 * This function initialize projectile tracking of a round so that it's path
 * can be drawn in debug mode. It may optionally include hit / explode /
 * deflected event handlers that spawn color coded spheres on each event,
 * green / red / blue, respectively.
 *
 * Arguments:
 * 0: Projectile to be tracked <OBJECT>
 * 1: Add projectile hit/explode/defelceted event handlers <BOOL> (default: true)
 * 2: Should the round track be blue. True results in blue traces, false in red <BOOL> (default: true)
 *
 * Return Value:
 * Nothing Useful
 *
 * Example:
 * [_projectile, false, false] call ace_frag_dev_addRound;
 *
 * Public: No
