#' Retrieves state/territory-level influenza statistics from the CDC (deprecated)
#' Uses the data source from the CDC' State-levelFluView
#' \url{} and provides state flu
#' reporting data as a single data frame.\cr
#' \cr
#' This function provides similar data to \code{\link{get_weekly_flu_report}} but
#' provides more metadata about the reporting sources and has access to more
#' historical infomation.
#' @param years a vector of years to retrieve data for (i.e. \code{2014} for CDC
#' flu season 2014-2015). Default value is the current year and all
#' \code{years} values should be >= \code{2008}
#' @return A \code{data.frame} of state-level data for the specified seasons
#' (also classed as \code{cdcstatedata})
#' @export
#' @note There is often a noticeable delay when making the API request to the CDC. This
#' is not due to a large download size, but the time it takes for their
#' servers to crunch the data. Wrap the function call in \code{httr::with_verbose}
#' if you would like to see what's going on.
#' @examples
#' get_state_data(2014)
#' \dontrun{
#' get_state_data(c(2013, 2014))
#' get_state_data(2010:2014)
#' httr::with_verbose(get_state_data(2009:2015))
#' }
