<li>[Added 2010-04-09] Preparations to support different ways to access the grammar:
currently we access a PGF server via JSONP, but I would also like to support AJAX,
and local/downloaded JavaScript grammars.
<li>[Added 2010-04-19] A text entry field appears when you click in
the sentence area (with a dashed border). This allows you to enter words by typing on
the keyboard. As you start typing word magnets that don't match what you are typing
are removed. When only one magnet remains, you can press enter to complete the word.
<li>[Added 2010-04-19] There is a menu for choosing the output language:
you can pick "All" to translate to all available languages, or pick one particular
language.
<li>[Added 2010-04-19] You can pass options to the function <code>start_minibar</code>
to customize the user interface. The default is
<code>{show_abstract:true,show_trees:true}</code> to show the abstract syntax of parsed
sentences, and to show icons that expand to syntax/parse trees next each translation.
These features can be turned off by setting the fields to <code>false</code>.
