+ * 1. To restrict hatches, override {@link #addDynamoToMachineList(IGregTechTileEntity, int)} and its cousins instead of overriding the whole
+ * {@link #getStructureDefinition()} or change {@link #checkHatches(IGregTechTileEntity, ItemStack)}. The former is a total overkill, while the later cannot
