/**
 * Represents a Crs specification. This is a simplified version from the actual GeoJSON specification, since the
 * GeoJSON specification allows for relative links to either URLS or local files in which the crs should be defined.
 * This implementation only supports named crs's: namely:
 * <pre>
 *  "crs": {
 *       "type": "name",
 *       "properties": {
 *             "name": "...yourcrsname..."
 *       }
 * }
 * </pre>
 * Besides the fact that only named crs is permitted for deserialization, the given name must either be of the form:
 * <pre>
 *  urn:ogc:def:EPSG:x.y:4326
 * </pre>
 * (with x.y the version of the EPSG) or of the form:
 * <pre>
 * EPSG:4326
 * </pre>
