Accurately measure and analyze the magnitude of earthquakes with D7S and PIC18F25J50

/*!
 * \file 
 * \brief Earthquake Click example
 * 
 * # Description
 * Intializes I2C module, LOG and GPIO structure, sets INT and PWM pins as 
 * input and sets CS pin as output.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Intializes of I2C driver and makes initial log.
 * 
 * ## Application Task  
 * This is an example that shows most of the functions that Earthquake click
 * has. Results are being sent to the Usart Terminal where you can track their 
 * changes.
