** CREATED:	10 May 2004
** AUTHOR: 	Mark Sheridan
** PURPOSE:	Java wrappers for JNI usage of the ECW config functions NCSecwSetConfig() && NCSecwGetConfig()
**			For some bizarre reason those calls were implemented as var args, since Java doesnt have var_args
**			it makes this code very verbose and prone to errors.
