Menu Manager for 1 or 2 Line Displays

This is a menu management library created as a front end to set parameters in embedded hardware control applications, leaving the back end under application control. It is suitable for text based displays (eg, LCD modules) with 1 or 2 lines available for display.

The library allows user code to define

Static menu definitions to minimized RAM footprint.
Callbacks for navigation and display control.
Menu inactivity timeout.
Auto start on key press or manual start by user code.
Input methods available for
- Boolean (Y/N) values.
- Pick List selection.
- Signed integers.
- Decimal floating point representation.
- Engineering units.

Menu managers in embedded systems are generally not the main function of the embedded application software, so this library minimizes the use of RAM and has a small memory footprint overall, leaving more space for what really matters.
