Geometry based Validation implementations.

This package is used to store simple Geometry based Validation implementations. Many of these will be simple FeatureValidation implementations concerned with limiting the defaultGeometry of a Feature.

At least a couple IntegrityValidation tests will also be implemented here performing such opperations as ensuring the defaultGeometries do not overlap for an entire FeatureType.

The constraints represented by many of these Validation checks are designed to provide similar coverage to the ArcSDE GeoDatabase appliaction. Where possible we have followed a similar naming convention to the ESRI product.
