New verification algorithm for Strict matching strategy

Hi,

I've implemented a small patch so that if you set the matching strategy to strict you also get verification errors, if your source object is missing some attributes relative to the destination.
It would be really cool if you could review the change, pull it to your repo and release a new version on maven central. If you do so I would like to use your library in a major project. And I would gladly talk to some guys to write a public blog post about it, if you like :)

Thx for the lib and have a nice weekend.
