Anaconda installation option

[mike-grayhat]

Seems like it would be beneficial to have an anaconda installation option, since it can handle system dependencies without root access.

The way forward seems to distribute BigARTM with pip instead (building the library in a cross-platform way and bundling all external dependencies in .whl file). There's some progress on this using cibuildwheel and Travis.

Currently, we have a Linux distribution: pip install bigartm and a provisional MacOSX distribution: pip install -i https://test.pypi.org/simple/ bigartm. Windows should be achievable as well, but it is a low-priority thing.

I would gladly elaborate if anyone wants to participate in this.
