 * \brief Proximity2 Click example
 * 
 * # Description
 * This is an example that shows the most important
 * functions that Proximity 2 Click has.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring Clicks and log objects.
 * Setting the Click in the default configuration.
 * 
 * ## Application Task  
 * Shows the most important proximity and ambient value.
