Functions
size_t &	RandIntInInt (const size_t &s, size_t &RIII, const int &seed=0)
	gives a random number such that \(0 \leq RIII < s\).
void	RandomPermutation (size_t *P, const size_t &len)
	Creates a random Lapack style Permutation P of size len.
template<class Field>
bool	CheckRank (const Field &F, const typename Field ::Element *A, const size_t &m, const size_t &n, const size_t &lda, const size_t &alledged_rank)
	Checks we got the right rank.
template<class Field>
void	RandomMatrixWithRank (const Field &F, typename Field ::Element *A, const size_t &m, const size_t &n, const size_t &lda, const size_t &rank)
	Builds a m x n random matrix of rank rank over field F.
template<class Field>
void	RandomMatrixWithDet (const Field &F, typename Field ::Element *A, const size_t &m, const size_t &lda, const typename Field ::Element &det)
	Builds a m x m random matrix of determinant det over field F.
