my presentation on basic Method::Signatures usage

I gave this at LA.pm on 3/20/13
I will give it again at YAPC on 6/4/13
this was generated with my patched version of Vroom
	hopefully Ingy accepts the patch soon
	once he does, I will upload the raw data I used to generate it
Merge branch 'master' of github.com:schwern/method-signatures
