Package igeo Description

Main package of iGeo library. This contains classes to handle three dimensional geometries, database of created internal objects and miscellaneous numerical operations. Old sub-package of igeo.geo (geometry package), igeo.core (core package), and igeo.util (utility package) are integrated into this main package.
