/*
This module defines the catalog of depreciation methods available for use in rules. It includes functions to build the full catalog of methods, as well as helper functions to create specific types of methods (e.g., MACRS, ACRS, GAAP). The main function `expandRuleSet` takes a rule set and adds the full method catalog to it, along with counts of methods by family.
