/**
 * ExtendedNamingStrategy works like the DefaultNamingStrategy but tries to create foreign key 
 * property names in a different way.
 * 
 * It looks for patterns like this .*_<forward>_<inverse> and uses the forward part for 
 * the foreign key name and inverse for the inverse foreign key name.
