docs: Builds out the main theme that we would like to use for all Apptentive UI, basing it on the
  existing app theme, and adding Apptentive's theme where it doesn't override the existing app's
  attributes. Finally, it forces changes to the theme using ApptentiveThemeOverride.
  @param context The context for the app or Activity whose theme we want to inherit from.
