Public Member Functions
	Slicer (DimType, ACDCGen &, const DVector &, const DVector &)
	The constructor takes the number of dimensions of the function approximated by the current cell, the ACDCGen object controlling the generation and the lower-left and upper-right corners of the cell to be sliced.

	Slicer (DimType Din, const Slicer &s, ACDCGenCell *cellin, const DVector &loin, const DVector &xselin, const DVector &upin, double fselin)
	The constructor used internally when diagonally chopped-off cells need to be sliced themselves.

	~Slicer ()
	Destructor.

void	divideandconquer ()
	Called from both constructors to do the actual work.

void	init ()
	Initialize the procedure, finding the slicing points around the current point.

void	slice ()
	Do the slicing and increase the overestimate of the function in the resulting cell.

double	shiftmaxmin ()
	After slicing a cell, find the maximum function value found in the resulting cell.

void	dohalf (DimType)
	Find the slice point of the current cell in the direction given.

void	checkdiag (ACDCGenCell *cell, DimType d, double lod, double upd)
	If split is in more than one dimensions check the overestimate for the chopped-off cell.

Public Attributes
DimType	D
	The dimension of the cell to be sliced.

DVector	lo
	The lower-left corner of the current cell.

DVector	up
	The upper-right corner of the current cell.

DVector	xcl
	The lower-left point found closest to the current point which gives a function value below the overestimate.

DVector	xcu
	The upper-right point found closest to the current point which gives a function value below the overestimate.

DVector	xhl
	The lower-left point furthest away from the current point which gives a function value abov the overestimate.

DVector	xhu
	The upper-right point furthest away from the current point which gives a function value abov the overestimate.

DVector	fhl
	The function values found for the xhl point.

DVector	fhu
	The function values found for the xhu point.

DVector	xsel
	The current point around which we are slicing.

double	fsel
	The function value in the current point.

ACDCGenCell *	current
	The current cell.

ACDCGenCell *	first
	The cell which resulted from the first slicing procedure.

DVector	firstlo
	The lower-left corner of the 'first' cell.

DVector	firstup
	The upper-right corner of the 'first' cell.

FncPtr	f
	A pointer to the function to be used.

double	epsilon
	The epsilon() value obtained from the controlling ACDCGen object.

double	margin
	The margin() value obtained from the controlling ACDCGen object.

multimap< double, DimType >	rateslice
	The dimensions to slice in rated by the resulting fractional volume of the resulting slice.

double	minf
	The minimu function value found in the current sliced cell (set by shiftmaxmin()).

bool	wholecomp
	If true, then the whole original cell should compensated in the continued generation.
