SPA Single page architecture lib design "Spah"

Assumptions:

• Host API is RESTish
• All host-client transfer is with JSON and all client-host transfer is with POST and multipart POST.
• Client-side progressive enhancements are the responsibility of the developer
• The server-side portion of the library will be ruby-based, and the client-side portion will be jquery-based, but the DTOs used to communicate between two will be thoroughly documented to allow drop-in replacement on either side.
