Lever Metadata

// Methods of Dealing with Metadata (such as whether a lever is turned on or off (powered or unpowered)

// 1:

	mf.Metadata.Levers = {
		"SideEastOff": 1,
		"SideWestOff": 2,
		"SideSouthOff": 3,
		"SideNorthOff": 4,
		"TopNorthOff": 5,
		"TopEastOff": 6,

		"SideEastOn": 9,
		"SideWestOn": 10,
		"SideSouthOn": 11,
		"SideNorthOn": 12,
		"TopNorthOn": 13,
		"TopEastOn": 14
	};

	// And a metadata library makes further usable functions

// 2:

	var block = mf.BlockAt(...);

	if (block.isPowered()) { ... }

	// Also to consider:

	var powered = block.isPowered();

	// powered is "undefined" if the type of block is not powerable, OR
	// isPowered is "undefined" if the type of block is not powerable

// 3:

	var block = mf.BlockAt(...);

	if (mf.Metadata.isPowered(block1)) { ... }

	// Also to consider:

	var powered = mf.Metadata.isPowered(block2)

	// powered is "undefined" if the type is not powerable, OR
	// a block passed to isPowered is asserted to be of a 'powerable' type.
