Changes the location of the current window. If `to` begins with '#' it only changes the document's hash. If passed more than 1 argument redirect will join them together with forward slashes.  ### Example  redirect('#/other/route'); // equivilent to redirect('#', 'other', 'route');
function() {
      var to, args = _makeArray(arguments),
          current_location = this.app.getLocation();
      if (args.length > 1) {
        args.unshift('/');
        to = this.join.apply(this, args);
      } else {
        to = args[0];
      }
      this.trigger('redirect', {to: to});
      this.app.last_location = [this.verb, this.path];
      this.app.setLocation(to);
      if (current_location == to) {
        this.app.trigger('location-changed');
      }
    }
