/***************************************************************************
*
* Function: Main
* Purpose: Calculate the FICON (Single Byte) CRC32
* Args: none
* Return Value: none
* Remarks:
* CRC32 Generator Polinomial:
* 0x104C11DB7
*
* x^0+x^1+x^2+x^4+x^5+x^7+x^8+x^10+x^11+x^12+x^16+x^22+x^23+x^26+x^32
*
* The CRC 32 polinomial is a linear feedback shift register that will
* generate a Maximal Length Sequence, implemented here using a lookup
* table, to reduce the number of shift and XOR operations.
