Advise please

Hi there, 

I've downloaded your code and run Composer and the PhpUnit tests

I now want to load up a page which utilises Memorize in my browser? Any advice is greatly appreciated.

this is what i have so far:

```
function __autoload($classname) {
    $filename = "src/". $classname .".php";
    include_once($filename);
}

$mem = new Memorize;
$mem->calcInterval(0);
```

but I get a fatal error
