Adds the ability to prefix nano-connections. What does that mean? Well, there will be an optional argument when establishing database connection:
var db = require("prefix-nano")(url[, prefix]);
What happens if a prefix is added?
It is basically prepended to all database names requested through that connection.
So we can do this to get a connection to the "voizee_dialplans"
-database:
var db = require("nano")(url, "voizee");
var dialplanDb = couchDb.use("dialplans");
