Desing proper build system

[Kirill Pavlov]

There are could be two ways to install the package: 1) with pip 2) build python files and copy them form this repo.

Python packaging is already in place: https://pypi.python.org/pypi/tabtools

While pip packaging is a common way to distribute python library, some of the servers might not have internet connection (private clouds) and "deployment" to such systems could be done only via file transfer to local ~/bin.
This task is about python executable files assembling, each of them should have no dependencies.
