		A GraphNode is a container with potentially several input and output slots allowing connections between GraphNodes. Slots can have different, incompatible types.

	<description>
		A GraphNode is a container. Each GraphNode can have several input and output slots, sometimes referred to as ports, allowing connections between GraphNodes. To add a slot to GraphNode, add any [Control]-derived child node to it.
		After adding at least one child to GraphNode new sections will be automatically created in the Inspector called 'Slot'. When 'Slot' is expanded you will see list with index number for each slot. You can click on each of them to expand further.
		In the Inspector you can enable (show) or disable (hide) slots. By default, all slots are disabled so you may not see any slots on your GraphNode initially. You can assign a type to each slot. Only slots of the same type will be able to connect to each other. You can also assign colors to slots. A tuple of input and output slots is defined for each GUI element included in the GraphNode. Input connections are on the left and output connections are on the right side of GraphNode. Only enabled slots are counted as connections.

				Sets properties of the slot with ID [param idx].
				If [param enable_left]/[param enable_right], a port will appear and the slot will be able to be connected from this side.
				[param type_left]/[param type_right] is an arbitrary type of the port. Only ports with the same type values can be connected and negative values will disallow all connections to be made via user inputs.
				[param color_left]/[param color_right] is the tint of the port's icon on this side.
				[param custom_left]/[param custom_right] is a custom texture for this side's port.
				[b]Note:[/b] This method only sets properties of the slot. To create the slot, add a [Control]-derived child to the GraphNode.
				Individual properties can be set using one of the [code]set_slot_*[/code] methods. You must enable at least one side of the slot to do so.
