Don't list non-public or hidden functions from methods() (bug #64066) * ov-classdef.cc (Fproperties): Use property name from property_map variable , which is already known, rather than calling get_name() method which causes cascade of multiple methods to be invoked. * ov-classdef.cc (F__methods__): Change function signature to return a flag "found" if input was a classdef class or instance. Add code to check "Access" and "Hidden" properties before including in list of methods. Add BIST test for __methods__. * methods.m: Use second output from __methods__ to determine whether __methods__ call was successful.
