Add eLife 2015;4:e12432 info

[mwatts15]

There is a report of regulatory data for C. elegans here:
eLife 2015;4:e12432
http://elifesciences.org/content/4/e12432v2
doi: http://dx.doi.org/10.7554/eLife.12432

This goal is to add the data to the PyOpenWorm data set using a DataTranslator with a DataWithEvidenceDataSource output type. The reference Document should include the above DOI, one or more URIs, authors, title, and publication date. Any other data that can easily be attached to the Document is also desired.
