* Name:     SidToTif.java
* Project:  
* Purpose:  Convierte una imágen MrSID en Tiff utilizando para la lectura
* 			 el wrapper jni-mrsid y para la escritura jni-gdal. Para el 
* 			 funcionamiento de este ejemplo es necesaria tambien la libreria
* 			 jmrsid.dll/libjmrsid.so.x.x.x así como las librerias de mrsid.
