Do not automatically convert Python integer types to Octave (see issue #56) * python_to_octave.cc (pytave::pyobj_to_octvalue): Drop automatic conversion of Python int and long types to Octave. * @pyobject/pyobject.m (pyobject.length, pyobject.size): Cast values to double. Adapt %!tests to changes. * @pyobject/cell.m, @pyobject/dummy.m, @pyobject/subsasgn.m, @pyobject/subsref.m, pycall.cc, pyeval.cc: Adapt usage examples and %!tests to changes.
