/*
* Author: Jaynus, NouberNou, Lambda.Tiger
* This function handles creating both random and targeted fragments as well as handling some of the performance optimizations.
*
* Arguments:
* 0: Position (posASL) of projectile <ARRAY>
* 1: Velocity of projectile <ARRAY>
* 2: Projectile CfgAmmo classname <STRING>
* 3: getShotParents of projectile at EH <ARRAY>
*
* Return Value:
* None
*
* Example:
* [getPosASL _projectile, velocity _projectile, typeOf _projectile, getShotParents _projectile] call ace_frag_fnc_doFrag;
*
* Public: No
