Feature: Implement FakeBasicPublishBatch.

[inbarbarkai]

Hi,

I've implemented a possible solution for the BasicPublishBatch.

Thanks for your contribution, I'll probably tweak it a bit (style), then merge it back into master.

@odalet You should add .editorconfig file and maybe style cop to define the code styles you want.
It would make PR's a little more easy.

Yeah, I know, but I didn't bother setting this up, and my own style preferences are somewhat personal and sometimes based on feeling rather than precise rules, hence probably difficult to hard code in a set of rules...
I also tend to understand other people's code by rewriting it. This rewriting is by no way a judgement by the way. So, and at least until I'm overwhelmed with PRs, I don't think I'll enforce anything for now.

Anyway, your contributions where very welcome!
