#' @details
#'
#' A light R wrapper around the elex command
#'
#' elexr provides an R interface for the elex package
#' (http://github.com/newsdev/elex/) to load election results from the
#' Associated Press Elections API.
#'
#' Rather than reinventing the wheel, this package simply runs \code{elex} in
#' a shell and loads the CSV output into a data frame. Because of this,
#' you'll need Python and to install elex by following the instructions at
#' \url{http://elex.readthedocs.org/en/latest/install.html}.
#'
#' You'll also need an API key for the API Elections API. You'll need to set
#' the \code{AP_API_KEY} environtment variable in your R session to be able to
#' retreive results.
#'
#' @examples
#' library(elexr)
#' Sys.setenv(AP_API_KEY = "YOUR_AP_ELECTIONS_API_KEY")
#' iowa_caucus_results <- results('03-01-2016')
