Fixing #2, plugin is not working out of the box

What I did:

1. removed the android sdk and  the android support library dependencies from the plugin itself
2. changed the way it selects what methods need to be overridden, so now it ignores final and private/package protected methods.
3. recreated the sample application
`mavenLocal()`is needed only for the buildscript. compile dependencies are fetched from central only.
