/**
 * A test class for {@link GeometryFactory} methods.

 * 

 * Usage:
 * 
 *  Create a class that extends this one and add the method:


 * 
 * {@literal @}BeforeClass

 * public static void initClass() {

 * 

 * 

 *   GeometryFactory.setMeshBuilder([a builder that provide suitable classes]);

 * }

 * 
 * 

 * If the object provided by the geometry factory are not from the same classes as the declared ones, tests will fail.
