/*
 * Author: PabstMirror
 * Handles lockpick functionality.  Three different functions:
 * "canLockpick": returns BOOL if lockpick is possible
 * "startLockpick": starts the process
 * "finishLockpick": on completions, opens the lock
 *
 * Arguments:
 * 0: Unit (player) <OBJECT>
 * 1: Vehicle <OBJECT>
 * 2: Function Type <OBJECT>
 *
 * Return Value:
 * "canLockpick" <BOOL>
 *
 * Example:
 * [ACE_player, ACE_Interaction_Target, 'canLockpick'] call ACE_VehicleLock_fnc_lockpick
 *
 * Public: No
