 /**
  * This class allow to specify specific behavior for blocks stored in blueprints:
  *
  * - what items needs to be used to create that block - how the block has to be built on the world - how to rotate the block - what extra data to store / load
  * in the blueprint
  *
  * Default implementations of this can be seen in the package buildcraft.api.bptblocks. The class BptBlockUtils provide some additional utilities.
  *
  * Blueprints perform "id translation" in case the block ids between a blueprint and the world installation are different. In order to translate block ids,
  * blocks needs to be uniquely identified. By default, this identification is done by:
  *
  * - the block simple class name - the tile simple class name (if any) - the block name
  *
  * In certain circumstances, the above is not enough (e.g. if several blocks share the same class and the same name, with no tile). In this case, additional
  * data may be provided by children of this class:
  *
  * - mod name - custom signature
  *
  * At blueprint load time, BuildCraft will check that each block id of the blueprint corresponds to the block id in the installation. If not, it will perform a
  * search through the block list, and upon matching signature, it will translate all blocks ids of the blueprint to the installation ones. If no such block id
  * is found, BuildCraft will assume that the block is not installed and will not load the blueprint.
