Fill in the architecture page

[winzou]

Hi,

Could you fill in the architecture page at http://docs.sylius.org/en/latest/book/architecture.html?

I'm interested in the project but it's quite difficult to dig in as, as far as I know, there is no global documentation.

Thanks a lot!

I would also really appreciate an architecture overview. Especially an explanation of the role of the CoreBundle and the ResourceBundle, which seem to integrate all bundles into a single project, would be useful. Big fan of Sylius, but difficult to dig in..

Indeed, please just add a quick explanation why there is a CoreBundle and a WebBundle in Sylius. Is this separation supposed to be kept on a long-term basis?
