DESCRIPTION
    Create javascript-code!

METHODS
  $self->add( $element )
    Adds a new element.

  $self->elements( )
    Returns a ref-array of all added elements.

  $self->output( )
    Returns the javascript-code.

  $self->output_for_html( < \%args > )
    Returns the javascript-code that can be directly embedded into
    html-code.

    Optimal \%args: Key-value pairs that reprensent attributes that will be
    associated to the script tag.

        print $code->output_for_html( { language => undef } );
