addition of SciPy2014 talk

**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.
Could phrase as building off of our experiences from pycogent (which was published prior to biopython), and inspired by the scikits and volume of data common in modern microbial ecology datasets. I think it is worth describing scikit-bio as having a fundamentally different direction than biopython: high bar for standards compliance, testing, coverage, living documentation, BSD-licensed, etc. Though, those are likely common goals, so that might be difficult to phrase
