Detailed Description

A helper to define a symbol's reference designator in a schematic.

This helper is required in a complex hierarchy because a symbol can be used more than once and its reference depends on the sheet path. This class is used to flatten the schematic hierarchy for annotation, net list generation, and bill of material generation.
