- nsf.c: * fixed a bug in "info parameter list|... name" when the named parameter is not found (returns now empty, before, it was returing the full list). * added flag "-nocomplain" to nsf::var::unset - nx.tcl * added "delete variable" analogous to "delete attribute" * unset instance variable for object-level "delete attribute" * extended regression test
- nx.tcl: * added support for "variable" on the class-level * added flag "noconfig" to object parameter options * parameters with "noconfig" are omitted in "info parameter syntax" and "info parameter list" * used switches for all configurable boolean options for "variable" and "attribute" * regularized the interface of "variable" and "attribute" * extended regression test
