pip install hexy` will only install required dependencies (only `numpy` for now).

and `pip install hexy[test]` will install dependencies needed for the tests.

Examples have been moved into their [own repo](https://github.com/redft/hexyexamples)

Package released into pip!

Starting from 1.3 because earlier versions wouldn't automatically install hexy's dependencies.
