[WIP] Release v 1.1

[sauln]

All changes for v1.1 are currently incorporated in the dev branch.

Included in the release is

• Official docs site : https://MLWave.github.io/kepler-mapper
• New visualization interface.
• Cover and nerve customizable interface

What needs to happen before we can deploy the next release :

• Setup docs to incorporate past versions and let you toggle between them
• Document new interfaces
  • Visualization
  • Cover
  • Nerve

I finally put some work into the docs (#56). I think v1.1 is just about ready to go out if no one has objections.
