#' rcaaqs: Tools for calculating CAAQS with air quality data
#' 
#' The rcaaqs package provides functions for the calculation of Canadian Ambient
#' Air Quality Standards (CAAQS).
#' 
#' @section rcaaqs functions:
#'   
#'   \itemize{ 
#'   \item General functions for doing things like formatting dates,
#'     filling in sequences, etc.
#'   \item Functions for step-wise calculation of CAAQS metrics for different 
#'     pollutants. Currently these are complete for fine particulate matter (PM2.5),
#'     ground-level ozone (O3), sulphur dioxide (SO2) and nitrogen dioxide (NO2).
#'   \item Functions for assigning metrics for different pollutants into 
#'     achievement and management categories.
