Better python package management (need input)

[Charlie Xia]

OBJECTIVE: create an automated way to create python package and documentation hosting and releases and make sure to overwrite user's old local installation after upgrade.

TODO: search how pip does package install and upgrade nicely and re-package ELSA in pip format. search how sphinx does documentation and transform wiki pages into sphinx.

This should be assigned to Jangping Zhu.

New package delivery will be primarily based on docker.
