AreaStyle	This class represents the complete style of an area for further comparison.
BasicSegmProvider	An artifact service provider for transforming the box tree to the area tree.
CollapseAreasOperator	This operator collapses the areas having only one (leaf) child.
Config	Segmenation algorithm configuration.
FindLineOperator	Detects the basic lines in the area tree and joins the appropriate areas so that a line is the smallest visual area.
FlattenTreeOperator	This operator flattens the tree: only the root area and the leaf areas are preserved.
GroupAnalyzer	A general analyzer to find area groups
GroupAnalyzerByDOM	A group analyzer that groups together the areas that are created by the same DOM element.
GroupAnalyzerByStyles	This group analyzer tries to expand the selected box to all directions stopping on whitespace separators.
GroupByDOMOperator	Creates groups of areas that share the same source DOM node.
HomogeneousLeafOperator	This operator joins the homogeneous-style leaf nodes to larger artificial areas.
MultiLineOperator	Detects sequences of aligned lines and joins them to a single area.
SegmentationAreaTree	A tree of visual areas created from a box tree.
Separator
Separators	Implementation of the operations with separators.
SeparatorSet	A generic set of horizontal and vertical separators for a page.
SeparatorSetHVS	A horizntal/vertical separator detection with shrinking.
SortByLinesOperator
SortByPositionOperator
SuperAreaOperator	Detects the larger visual areas and creates the artificial area nodes.
TreeOp	Implementation of basic area and tree opeations used by the operators.
