Module Name:
- CascadiaSettings.hpp

Abstract:
- This class acts as the container for all app settings. It's composed of two
        parts: Globals, which are app-wide settings, and Profiles, which contain
        a set of settings that apply to a single instance of the terminal.
  Also contains the logic for serializing and deserializing this object.
