Last name changes and other minor details in DESCRIPTION file


* Change format for last name to match Leonardo's use in academic papers
* Added  type, date, URL, bugreports fields to DESCRIPTION file. Changed to using Authors@R format with middle names. Note Alyssa did not use her middle name in this package but did use it at http://biostatistics.oxfordjournals.org/content/early/2014/01/06/biostatistics.kxt053.full So I added it but she might not want it.
* Bump version to 1.1.1 to feed it to Bioconductor
