Used to identify a single chain split into multiple units.
Reference chainIndex from model for faster access.
invariant ID stays the same even if the Operator/conformation changes.

A bulding block of a structure that corresponds to a "natural group of atoms" (most often a "chain") together with a transformation (rotation and translation) that is dynamically applied to the underlying atom set.
An atom set can be referenced by multiple different units which makes construction of assemblies and spacegroups very efficient.
