JTSFacade

```
public class JTSFacade
extends java.lang.Object
```
Instead of calling individual methods of JTS (JTS Topology Suite), this singleton facade allows gvSIG users to centralize all JTS computational geometry operations in one only class. This is useful to ensure certain operations (for example, geoprocessing operations could cause robustness problems, so JTS allows to use enhanced precission operations, this facade forces to use these enhanced precision operations)
