Hey,

using the AreaChart class the Util class is not found.

Reason

use \koolreport\core\Utility;

but in processOptions() Util is used. Changing to Utillity everything works fine.

protected function processOptions()
    {
        $options = $this->options;

        $axes = Util::get($this->params, "axes", []);
        foreach ($axes as $k => $v) {
            $axes[$k]["id"] = $k;
        }
        $axes = array_values($axes);
        if (!empty($axes)) {
            $axesKey = "yAxes";
            Util::set($options, ["scales", $axesKey], $axes);
        }

        return $options;
    }

I have just bought the package - please propvide an update.

Cheers Patrick
