Even if you had every datum informations (name, EPSG code, everything), this is
not suffisient for getting a CoordinateReferenceSystem... Many CRS use the same
datum.
If you don't want to deal with epsg-hsql and your CRS never change, you can:
* Dump it in WKT format (using CoordinateReferenceSystem.toString())
and parse it later using CRS.parseFromWKT(String).
* Or serialize it and deserialize in your application.
