This library provides an easy to use, buffered, hardware-filtered CAN interface for
high performance CAN applications.  Provides automatic reception of messages via CAN RX interrupt
into a rx ring buffer.  Provides automatic transmission of messages via CAN TX interrupt.
 
@File CAN_Filter_LUT.h: Contains the formatted lookup tables to program the onboard CAN acceptance filters
