Create a fully isolated CAN interface with ADM3053 and STM32F407VGT6

/*!
 * \file 
 * \brief CanIsolator Click example
 * 
 * # Description
 * This is a example which demonstrates the use of Can Isolator Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring clicks and log objects.
 * 
 * ## Application Task  
 * Checks if new data byte has received in RX buffer ( ready for reading )
 * and if ready than reads one byte from RX buffer.
 * In the second case, the application task writes message data via UART.
 * Results are being sent to the Usart Terminal where you can track their changes.
