/**
 * Deserialize an object/*w  w  w. j a  v a 2  s  . c  o m*/
 * @param filename The file name where the object was serialized.
 * @return An object. Most likely a posterior cast will be needed.
 * @throws FileNotFoundException if the ser file was not found
 * @throws IOException ?
 * @throws ClassNotFoundException Very unlikely to appear. The object class is always there.
