Detailed Description

This class keeps track of modules and interfaces that need to be renamed, as well as module ports, parameters, declarations and verif labels that need to be renamed.

This can happen either due to conflicts between them or due to a conflict with a Verilog keyword.

Once constructed, this is immutable.
