In constructive: Display Idiomatic Code to Construct Most R Objects

#' Constructive options for class '.CLASS1.'
#'
#' These options will be used on objects of class '.CLASS1.'.
#'
#' Depending on `constructor`, we construct the object as follows:
#' * `".CONSTRUCTOR."` (default): We build the object using `.PKG::CONSTRUCTOR.()`.
#' * `"next"` : Use the constructor for the next supported class.
#'
#' @param constructor String. Name of the function used to construct the object.
#' @param ... Additional options used by user defined constructors through the `opts` object
#' @return An object of class <constructive_options/constructive_options_.CLASS1.>
