A reed solomon error-correcting encoding constructor is created by
passing as Galois Field with of size equal to the number of code
words (symbols) in the alphabet (the number of values in each
element of arrays that are encoded/decoded).
@param field A galois field with a number of elements equal to the size
of the alphabet of symbols to encode.
