/*
	DMS_fnc_FillCrate

	Inspired by WAI: https://github.com/nerdalertdk/WICKED-AI
	created by eraser1

	Usage:
	[
		_crate,						// OBJECT: 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
		_rareLootChance				// (OPTIONAL) NUMBER: Manually define the percentage chance of spawning some rare items.
	] call DMS_fnc_FillCrate;

	If the "_lootValues" parameter is a number or a string, the function will look for a value defined as "DMS_CrateCase_*", where the "*" is replaced by the "_lootValues" parameter. EG: DMS_CrateCase_Sniper.

	Otherwise, the "_lootValues" parameter must be 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, if you want to configure the list from which weapons, items, and backpacks are selected, it should be of the form:
	[
		[
			_number_of_weapons,
			[
				"wepClassname1",
				"wepClassname2",
				...
				"wepClassnameN"
			]
		],
		[
			_number_of_items,
			[
				"itemClassname1",
				"itemClassname2",
				...
				"itemClassnameN"
			]
		],
		[
			_number_of_backpacks,
			[
				"backpackClassname1",
				"backpackClassname2",
				...
				"backpackClassnameN"
			]
		]
	]

	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.

	OR:
		[
			_customLootFunctionParams,
			_customLootFunction
		]
		In this case, "_customLootFunctionParams" is passed to "_customLootFunction", and the custom loot function must return the loot in the form:
		[
			[
				weapon1,
				weapon2,
				[weapon_that_appears_twice,2],
				...
				weaponN
			],
			[
				item1,
				item2,
				[item_that_appears_5_times,5],
				...
				itemN
			],
			[
				backpack1,
				backpack2,
				[backpack_that_appears_3_times,3],
				...
				backpackN
			]
		]
