wip/galoisfieldarth 2006 NetBSD

A simple library written in the C++ language for performing arithmetic over Galois fields.The arithmetic can be in the form of either elements or polynomials over a specified Galois field.The library is optimised to run in one of two modes, normal or LUT mode. In the LUT mode performance is increased dramatically at the cost of large consumption of memory. The library can be used in but not limited to such fields as cryptography, error correcting codes and computational analysis.
