/***************************************************************************



* 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.
