Detailed Description

Here, we define the 2D geometric algortihms. they are based on the boost library.

The idea is to define complex geometry based on shapes, usually multi-polygon using boost library. we propose only very simple combinaton that the region is composed of shapes without intersection. That is, the shapes are those contain each other or without overlap. This strict requirement suggests that complex shapes should be finished already in modeling using related binary operations before it is included.
