#' ccrtm: Coupled Chain Radiative Transfer Models.
#' 
#' A collection of radiative transfer models that can form
#' a coupled chain to model radiative transfer across multiple
#' spatial scales from leaf to canopy to stand.
#'
#' Currently implemented models:
#'
#'  \itemize{
#'
#' \item [1] = PROSPECT 5, 5B and D
#' \item [2] = FOURSAIL, and FOURSAIL2 
#' \item [3] = FLIM 
#'
#' }
#'
#' Currently being tested or to be implemented models
#'
#'  \itemize{
#'
#' \item [1] = LIBERTY, PROCOSINE
#' \item [2] = INFORM
