**NOT READY FOR MERGE** 

Just posting for easy review by others. Note that this makes use of the code in [@fperez's nb-slideshow-template](https://github.com/fperez/nb-slideshow-template). The ``install-support.ipynb`` notebook from that repo will need to be run once, prior to this presentation working in slideshow mode.
Hmm... the classname is extended because of the current skbio module structure. Damn. I think we can get around that with making use of metaclasses to get something like `<class 'skbio.core.alignment.Alignment'>` instead.
