jester.js

/* The standard way of declaring a model is:
   Jester.Resource.model("User")
   This assumes "user" as a singular form, and "users" as a plural.
   Prefix rules: If no prefix given, default to the local domain
     If prefix given, and prefix begins with "http:", take that as the entire prefix,
        otherwise, treat it as a relative path and append it to the default prefix, adding a slash if necessary.
     Example valid prefixes, assuming current domain is "www.thoughtbot.com:8080":
       "http://www.google.com" => http://www.google.com
       "" or null => http://www.thoughtbot.com:8080
       "public/forum" => http://www.thoughtbot.com:8080/public/forum
       "/public/forum" => http://www.thoughtbot.com:8080/public/forum
