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 } );
