/*----------------------------------------------------------------------

LuminosityBlockPrincipal: This is the class responsible for management of
per luminosity block EDProducts. It is not seen by reconstruction code;
such code sees the LuminosityBlock class, which is a proxy for LuminosityBlockPrincipal.

The major internal component of the LuminosityBlockPrincipal
is the DataBlock.
