This fixes the segmentation fault when converting numpy and Eigen.
The reason is that NumpyEigenConverter.hpp includes numpy/arrayobject.h, and for
the numpy's C-API to work in multiple files we need to define NO_IMPORT_ARRAY
before including numpy/arrayobject.h in all the source files but the one that
defines the module initialization (exportgtsam.cpp in out case), as explained
here:
http://docs.scipy.org/doc/numpy/reference/c-api.array.html#importing-the-api
Note that PY_ARRAY_UNIQUE_SYMBOL, also needed to work multifile, is already
defined on NumpyEigenConverter.hpp.
Just noticed several handwritten files here. I'm reverting the python module to
use these handwritten files to later add the files I was wrapping to the same
framework.
Classes from geometry were wrapped for an old C++ interface, so several
boost python's .def(...) were commented out.
Conflicts:
python/gtsam/.gitignore
Nonlinear factor is pure virtual, so we need to declare a wrapper, even
if we don't export anything from it.
Also, we don't make explicit all the chain of inheritance from BetweenFactor,
since it looks like exporting inheritance directly from NonlinearFactor allows
adding it to NonlinearFactorGraph.
