	Usage:
	[
		_crate,						// The crate object
		_lootValues					// Array, string, or number. String or number refers to a crate case in config.cfg; array determines random crate weapons/items/backpacks
	] call DMS_fnc_FillCrate;
	
	Loot values can be a number or a string with a corresponding "Crate Case" defined in the config. EG: DMS_CrateCase_Sniper. Or it can be an array.
	
	In the array, the loot values are defined as:
		[
			_weapons,
			_items,
			_backpacks
		]

	Each loot argument can be an explicitly defined array of weapons with a number to spawn, or simply a number and weapons defined in the config.sqf are used.

	For example, _weapons could simply be a number, in which case the given number of weapons are selected from "DMS_boxWeapons",
	or an array as [_wepCount,_weps], where _wepCount is the number of weapons, and _weps is an array of weapons from which the guns are randomly selected.
