* var options = { validate: true, name: "bar" };
* @result settings == { validate: true, limit: 5, name: "bar" }
* @desc Merge defaults and options, without modifying the defaults
*
- * @example var defaults = { validate: false, limit: 5, name: "foo", nested: {depth: false} };
- * var options = { validate: true, name: "bar", nested: {depth: true} };
- * var collision_resolver_fn = function(target, mergee) {
- * // combine nested Objects, in this case the object being merged takes priority
- * return jQuery.extend({}, target, mergee);
- * }
- * var settings = jQuery.extend({}, collision_resolver_fn, defaults, options);
- * @result settings == { validate: true, limit: 5, name: "bar" }
- * @desc Recursively merge defaults and options, without modifying the defaults
- *

* @param Object target The object to extend
- * @param Function (optional) collision resolution function. Hook to extend the merging behavior of $.extend(). See example.
