tiny demo project using ps-lite

[jzhang533]

is there any project demostrating abilities and best practices of ps-lite ?
mxnet is great, but too heavy for understanding ps-lite.
I am expecting one thousand lines codes which using ps-lite to enable multi-cards training.

If you just want to know more about ps-lite in a tiny example, dist-lr does it. It implements a distributed LR based on ps-lite (currently, only local version, but easy to extend to dist).
