Detailed Description

Utility class to calculate checksums as CRCs (Cyclic Redundancy Check).

Currently Only the CCITT16 is claculated, add functions when necessary.

Note

The type of checksum is defined by the polynomial used: for the CCITT16 it is x^16+x^12+x^5+1 = (1) 0001 0000 0010 0001 = 0x1021 this hex code can be replaced in the function to calculate different types of CRCs see http://en.wikipedia.org/wiki/Cyclic_redundancy_check for a list of polynomials
