0024899: Time of computation of intersection points with help of class BRepIntCurveSurface_Inter is big.

Browse Source 
Sorting by intersection of bounding boxes of faces with line or box built for curve was added.
Recursive call method Find() was replaced on sequential call.
Added method Init  to initialize algorithm by separate curve for intersection of shape by multiple curves.
Added possibility to intersect shape by multiple curves in DRAW command.

Added test case bugs/modalg_5/bug24899
