GenericGFPoly

class GenericGFPoly(field: GenericGF, coefficients: IntArray)

Represents a polynomial whose coefficients are elements of a GF. Instances of this class are immutable.

Much credit is due to William Rucklidge since portions of this code are an indirect port of his C++ Reed-Solomon implementation.
