Shows how to use xtd::console::key_available and xtd::console::read_key methods.

    // for the sake of this example we'll merely pause for a quarter second.

// This example produces results if user stroke 'h', 'e', pagge_up, down_arrow, and 'x' keys
//
// Press a key to display; press the 'x' key to quit.
// You pressed the 'h' key.
//
// Press a key to display; press the 'x' key to quit.
// You pressed the 'e' key.
//
// Press a key to display; press the 'x' key to quit.
// You pressed the 'page_up' key.
//
// Press a key to display; press the 'x' key to quit.
// You pressed the 'down_arrow' key.
//
// Press a key to display; press the 'x' key to quit.
// You pressed the 'x' key.
