How Does a Block Provider Work With Gitit?

With block, i try to keep my blocks like where all the logic is. I put those into lazy singletons and so they get created whenever i need to create my block. And what i like about block is that it's very clear that i can see where are my blocks. E, an alternative iser is, indeed, you could use scopes, but er, i think scopes are much more useful,. inde, a business logic if i want to or  if i want to control object lifetime - for example here.
