Public Member Functions
Constructors, Destructor

	TVector (size_t _size, const TRing *_ring, string _name="unnamedVector")
	Creates a zero TVector of size size with elements in _ring. (vector[i] = TNum::Zero, i is in 0,..,(size-1).
template<class _istream >
	TVector (const TRing *_ring, _istream &_vectorStream, string _name="unnamedVector")
	Creates TVector from a stream, with elements in _ring. Currently only integer entries are supported. Required stream format style is like : {1,22,33,...}.
	TVector (string _vectorStr, const TRing *_ring, string _name="unnamedVector")
	Creates TVector from a string, with elements in _ring. Currently only integer entries are supported. Required string format style is like : {1,22,33,...}.

void	fillZero ()
	fill all elements with TNum::Zero
void	randomInit (long *_pRandomSeed)
	Init all entries with random TRing elements. _pZufallSeed has to point to a random seed, which is used by ran2() random generator randomInit. Only implemented for (ring1->getEpsPrecision==0).
