title: Scan the classpath for classes with custom annotation
body: <p>For example if I have annotation <code>@MyOwnAnnotation</code> and have these classes in my classpath, so that I could scan classpath possibly with some kind of filter (example. scan only packages starting with <code>my.own.app.*</code>)  and get list of all classes with annotation <code>@MyOwnAnnotation</code>? I'm using guice as injection framework and I don't use Spring.</p>
