cid(object, optionalObjectType)

Get a unique identifier for the object, optionally prefixed by a type name.

Once set, the unique identifier does not change, even if the type name changes on subsequent calls.

var cid = require("can-cid");
var x = {};
var y = {};

console.log(cid(x, "demo")); // -> "demo1"
console.log(cid(x, "prod")); // -> "demo1"
console.log(cid(y));         // -> "2"
