/**

 * Esta clase se encarga de hacer la conversion entre Wkt e IProjection.

 *

 * El uso se hace mediante dos llamadas estaticas que son: convertIProjectionToWkt y

 * convertWktToIProjection.

 *

 * Antes de usarlos, hay que saber si tenemos acceso a gvSIG e intentar coger el factory desde all?.

 * Ya que su uso consume tiempo y espacio de memoria y es preferible reaprovechar ese objeto ya

 * creado. Esto se hace con setCRSFactory.

 *

 * En caso de no asignarse el ya existente, el crear? uno interno y lo dejara en una variable estatica.
