module app.controllers
{
    export class testCtrl implements IController
    {
        constructor()
        {
            console.log("Test Controller");
        }
    }
}

app.registerController('testCtrl');

is there a way to put

module app.controllers
{
    export class testCtrl implements IController
    {
        constructor()
        {
            console.log("Test Controller");
        }
    }
}

app.registerController('testCtrl');

in a different file?
