/*

An example of an InkHUD applet.
Tells us when a new text message arrives.

This applet makes use of the Module API to detect new messages,
which is a general part of the Meshtastic firmware, and not part of InkHUD.

In variants/<your device>/nicheGraphics.h:

    - include this .h file
    - add the following line of code:
        windowManager->addApplet("New Msg", new InkHUD::NewMsgExampleApplet);
