<h2>SyntaxCheckService</h2>
<p>
    Implement the syntax check service.
</p><p>
    Plugins can add other languages to the syntax check by calling addLanguage
    and support of an extra checker module on the client side which has to
    connect directly to the background service.
</p><h3>Signals</h3>

emited when the syntax check was done.
