Where do proxies go in the MVC structure? Do they get automatically loaded like controllers, views, models, stores, etc... ?

BTW - From looking at the Kiva example, it appears that custom proxies are manually configured but I really don't understand it. Specifically, I don't understand why the proxy definition/class is in lib/KivaProxy.js. I would think it would be in something like proxy/Kiva.js and that the model would reference it. Can someone please explain?
