  # ModuleElement struct creates an argument objects which is needed in
  # generate_module_contents_json method. It takes 3 parameters a Proc and
  # additional options wich can be extended.
  # :element => name of module element in plural
  # :children => bolean if element has children elements in report
  # :locals => an array of names of local variables which are passed in the view
  # :coll => a prock which the my_module is passed and have to return a
  #          collection of element
  # :singular => true by defaut change the enum type to singular
  #              needed when querying partials by name
