I am pleased to announce the first official release of randomgen. The version number reflects the NumPy compatibility target.

* Release based on `RandomState` in NumPy 1.14.
* Successor to `randomstate` using a new architecture.
* Similar structure to `RandomState` using `RandomGenerator`
* Pluggable basic RNG
* Low-level interface via CFFI or CTypes
* Passes all tests still relevant for `RandomState` using `MT19937`

* Release to trigger doc build

Re-release of 0.1 to allow docs to correctly build.
