Finally `component` has been renamed to `name`, i.e. there are some
  parsers that have a `name`. If a parser has a name this is used to
  describe nodes in the S-Expression of XML-Representation of the AST-Tree.
  Only in this latter sense, they are components of the AST-tree, but
  it is nicer to speak of a named parser.
  Names can be assign to Parsers on object initialization, or - more
  elegantly - they will be assigned by instantiating the Grammar class
  (which is always a descendant of the ParserHeadquarter class).
  In this case, those parsers that have been assigned to a
  class variable of the Grammar class will receive the variable's name
  as their parser name. This makes the python-compiled grammars more
  readable, because they are need not to be clutterd with (redundant)
  name assignments.
