/*
* Author: Jaynus, NouberNou, Lambda.Tiger
* This function creates fragments randomly spreading out from an explosion to
* a maximum of 15
*
* Arguments:
* 0: Position of fragmenting projectile ASL <ARRAY>
* 1: Velocity of the fragmenting projectile <ARRAY>
* 2: Height (AGL) of the fragmenting projectile <SCALAR>
* 3: Type of fragments to generate
* 4: Remaining fragment budget <SCALAR>
* 5: Shot parent <ARRAY>
*
* Return Value:
* None
*
* Example:
* [getPosASL _proj, velocity _proj, 50, 50, [], 1, [player, player]] call ace_frag_fnc_doFragRandom;
*
* Public: No
