/**
 * Interface for grouping multi-block structures to a single energy net delegate.
 * 
 * The energy net uses TileEntity to refer to a specific xyz+world position. If multiple of those
 * positions should belong to the same functional structure, i.e. they consume or produce energy
 * only once for the whole multi-block instead of once per every single block, this interface
 * allows to do so.
 * 
 * The tile entity implementing IMetaDelegate has to be added/removed to/from the energy net
 * instead of every single sub-TileEntity. The energy net interaction will be handled by the
 * IMetaDelegate TileEntity as well.
 * 
 * The sub tile array TileEntity[] just provides optional connectivity (IEnergyAcceptor,
 * IEnergyEmitter) and mandatory position (x, y, z, World) data.
 * If the connectivity data on the sub tile is missing, the meta delegate is queried instead.
 * 
 * See ic2/api/energy/usage.txt for an overall description of the energy net api.
