Module Name:
- Profile.hpp

Abstract:
- A profile acts as a single set of terminal settings. Many tabs or panes could
  exist side-by-side with different profiles simultaneously.
- Profiles could also specify their appearance when unfocused, this is what
  the inheritance tree looks like for unfocused settings:

                +-------------------+
                |                   |
                |Profile.defaults   |
                |                   |
                |DefaultAppearance  |
                |                   |
                +-------------------+
                   ^             ^
                   |             |
