Convert scalar struct into Python dict (fixes issue #57)
* oct-py-types.cc, oct-py-types.h: New files for conversion of objects between
Octave and Python APIs.
* Makefile.am (COMMON_SOURCE_FILES, PYTAVE_HEADER_FILES): Include new files.
* octave_to_python.cc (pytave::octvalue_to_pyobj): Add case to handle scalar
struct instead of struct array.
* @pyobject/pyobject.m: Add %!tests for pyobject from scalar struct and %!error
tests for failure with struct array.
