dojo.delegate = function(obj, props){

// description:
// This is a small implementaton of the Boodman/Crockford delegation
// pattern in JavaScript. An intermediate object constructor mediates
// the prototype chain for the returned object, using it to delegate
// down to obj for property lookup when object-local lookup fails.
// This can be thought of similarly to ES4's "wrap", save that it does
// not act on types but rather on pure objects.
// obj:
// The object to delegate to for properties not found directly on the
// return object or in props.
// props:
// an object containing properties to assign to the returned object
// returns:
// an Object of anonymous type
// example:
// | var foo = { bar: "baz" };
// | var thinger = dojo.delegate(foo, { thud: "xyzzy"});
// | thinger.bar == "baz"; // delegated to foo
// | foo.thud == undefined; // by definition
