Overview

This class parses all of the VAProfile exception keys from config/locales/exceptions.en.yml and saves them to an instance variable. For performance reasons, the Singleton Pattern is used. This allows the file system to be hit one time, when a server instance is initialized. From that point forward, the exception keys are saved to an instance variable in this class, thereby eliminating the need for the file system to be hit repeatedly.
