This tag provides a bit level identity for binary data. It must attached to a packet or chunk as a region tag. The identity of a bit in the region can be calculated by adding the offset of said bit to the identityStart field of the tag.

The tag is split and merged automatically when the data is split or merged. This allows one to have an effective globally unique identity for each bit in the simulation. This tag allows following the bits in the network through the whole lifetime of the simulation.
