py3d conflicts with pyigl

[qianyizh]

Ubuntu 16.04
Open3D developing branch
libigl developing branch
Get segment fault from importing.

>>> import py3d
>>> import pyigl

Probably due to inconsistent pybind11 versions and naming conflict.

[qianyizh]

The reason seems to be double binding of std::vector<int>. Both Open3D and libigl does it and it conflicts. This behavior has been thoroughly discussed in:
pybind/pybind11#919

An update to the latest pybind11 should resolve this.
It is related to #18

Sounds good. Specifying name space like

import py3d as py3d

can avoid conflicts too, right?

[qianyizh]

Tried. Did not work.
pybind11 does something with the global environment.

[syncle]

Good to know. I tried to upgrade pybind11 a month ago, but it seems like non-trivial task.
Do you think upgrading pybind is top priority before release?

[qianyizh]

No. It is lower priority.
