/**
 * Gets the Coordinate Reference System (CRS) from the given geometry.

 * <ul>
 *   <li>Geometry {@linkplain Geometry#getUserData() user data} is an instance of {@code CoordinateReferenceSystem}.</li>
 *   <li>{@linkplain Geometry#getUserData() user data} is a (@link Map} with a value for the {@value #CRS_KEY} key.</li>
 *   <li>Geometry SRID is strictly positive, in which case it is interpreted as an EPSG code.</li>
 * </ul>
 *
 * If none of the above is valid, {@code null} is returned.
 *
 * @param  geometry the geometry from which to get the CRS, or {@code null}.
 * @return the coordinate reference system, or {@code null} if none.
 * @throws FactoryException if the CRS can not be created from the SRID code.
