 * \brief Terminal Click example
 * 
 * # Description
 * This example showcases how to initialize, configure and use the Terminal Click. It is a simple
 * GPIO Click which is used like an adapter for connecting and stacking other Clicks and external
 * equimpent.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the Click and logger modules.
 * 
 * ## Application Task  
 * This function sets the output on all the pins (one by one) on the left side to high, going
 * from top to bottom and then does the same with the ones on the right side, after which it 
 * sets all pins to high and after one second sets them back to low.
