	BlisHeurRound ()
	Default Constructor.
	BlisHeurRound (BlisModel *model, const char *name, int strategy)
	Constructor with model - assumed before cuts.

	Destructor.
	BlisHeurRound (const BlisHeurRound &)
	Copy constructor.
virtual BlisHeuristic *	clone () const
	Clone a rounding heuristic.
virtual void	setModel (BlisModel *model)
	update model (This is needed if cliques update matrix etc).
virtual bool	searchSolution (double &objectiveValue, double *newSolution)
	returns 0 if no solution, 1 if valid solution with better objective value than one passed in Sets solution values if good, sets objective value (only if good) This is called after cuts have been added - so can not add cuts
