In seawaveQ: SEAWAVE-Q Model

#' An R package for the U.S. Geological Survey seawaveQ model, a 
#' parametric regression model specifically designed for analyzing 
#' seasonal- and flow-related variability and trends in pesticide 
#' concentrations.  See Vecchia and others (2008) for the original 
#' description of the model and see Sullivan and others (2009), 
#' Vecchia and others (2009), Ryberg and others (2010), 
#' Ryberg and others (2014), Ryberg and Gilliom (2015), 
#' and Oelsner and others (2017) and for applications of 
#' the model.
