* Esta clase abstracta es el ancestro de todas las clases que proporcionan |

* soporte para ficheros raster georeferenciados.<br> |
|
| 26 |
* Actua tambien como una 'Fabrica', ocultando al cliente la manera en que |
|
| 27 |
* se ha implementado ese manejo. Una clase nueva que soportara un nuevo |
|
| 28 |
* tipo de raster tendr?a que registrar su extensi?n o extensiones usando |
|
| 29 |
* el m?todo @see registerExtension.<br> |
