##' Get a list of bills according to sponsor(candidate) and year
##'
##' This function is a wrapper for the Votes.getBillsBySponsorYear() method of the PVS API Votes class which grabs a list of bills that fit the sponsor's candidateId and year. The function sends a request with this method to the PVS API for all candidate IDs and years given as a function input, extracts the XML values from the returned XML file(s) and returns them arranged in one data frame.
##' @usage Votes.getBillsBySponsorYear(year, candidateId)
##' @param year a character string or list of character strings with the year(s)
##' @param candidateId a character string or list of character strings with the candidate ID(s) (see references for details)
##' @return A data frame with a row for each bill and columns with the following variables describing the bill:\cr bills.bill*.billId,\cr bills.bill*.billNumber,\cr bills.bill*.title,\cr bills.bill*.type.
##' @references http://api.votesmart.org/docs/Votes.html\cr
##' Use Candidates.getByOfficeState(), Candidates.getByOfficeTypeState(), Candidates.getByLastname(), Candidates.getByLevenshtein(), Candidates.getByElection(), Candidates.getByDistrict() or Candidates.getByZip() to get a list of candidate IDs.

##' # get additional biographical data on Barak Obama

##' \dontrun{obama}
