// Implementation note: the BlockConstruct routine has been customized
// for ZZ_p so that when a vec_ZZ_p is grown, space for the needed
// elements is allocated in one contiguous chunk. This saves on calls to
// malloc and free, and should also yield better locality of reference.
// One connsequence of this is that swapping an element of a vec_ZZ_p
// with another ZZ_p can not be implemented by pointer swap, and will in
// this case be done by copy.
