Syntax:: [array] call BIS_fnc_arrayShift
Parameters:: array: Array - NOTE: given array must be within an array (e.g [[10, 20, 30]] call BIS_fnc_arrayShift)

Example 1:: private _myArray = ["2", "report", "status"]; _removedElement = [_myArray] call BIS_fnc_arrayShift; // array is -within an array- _removedElement == "2"; // true _myArray isEqualTo ["report", "status"]; // true
