GRS constructor should copy list of eval pts and column multipliers

[Johan Rosenkilde]

F = GF(59)
n, k = 40, 12
evals = F.list()[:n]
colmults = [F.one()]*n
C = GeneralizedReedSolomonCode(F, n, k, evals, colmults)
while evals:
    del evals[0]
    del colmults[0]
assert len(C.evaluation_points()) == n
assert len(C.column_multipliers()) == n

<BOOM>
