In constructive: Display Idiomatic Code to Construct Most R Objects

#' Constructive options for class 'S7_property'
#'
#' These options will be used on objects of class 'S7_property'.
#'
#' Depending on `constructor`, we construct the object as follows:
#' * `"new_property"` (default): We build the object using `S7::new_property()`.
#' * `"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_S7_property>
