Defines functions pos_names

Documented in pos_names

#' Provide pre-extracted names for Provider of Service file, years 2000-2010
#' 
#' @param year A year in the range 2000-2010
#'   
#' @return A list of names for the POS dataset in the year specified, in the 
#'   order that the raw data lists them
#'   
#'   This function returns the results of running \code{pos_names_extract} on 
#'   the layout and raw data files for the chosen year. For years 2000-2010, the
#'   raw data had unhelpful, generic, sequentially numbered variable names.
#'   These can be calculated fresh by calling \code{pos_names_extract} on the
#'   imported dataframe and its corresponding layout .txt file. Alternately,
#'   this function returns the names compiled by that function for years
#'   2000-2010, saving the user a step.
