Tali Zvi 51e1719e9b Due to a bug in MSVC, the Point_plus_rep could not be templated with 
a subdivision class. Therefore, I modified the class so it is templated
with traits and vertex_handle classes instead.
 2002-10-24 14:27:24 +00:00

Ester Ezra 14d36e43da The base class of the Sweep line package. 
Includes basic types and common functions.

The basic types provided are:
1.  Curve_node. A curve of the sweep line which consists the input curve and a list
	of the intersection points along it.
2. Intersection_point_node. A point of the arrangement induced by the input curve.
	Each such point holds all Curve_nodes enamating from it, ordered in a counrer
	clockwise order.
3. less_xy. A binary predicate orders two points lexicographically by their xy values.
4. less_yx. A binar predicate orders two Curve nodes on the status line.

5. Event queue: The queue structure of the sweep line algorithm.
6. Status line: The status structure of the sweep line algorithm.

The basic functions provided are:
1. handle_one_event: Handle on event from the event queue.
2. handle_overlapping_curves: Handle overlapping curves on the status after handling an event.
3. check_status_neighbors_intersection: Check for new neighbors on the status line and create new
events if needed.
