/**
 * Recursively merges own enumerable properties of the source object(s), that
 * don't resolve to `undefined` into the destination object. Subsequent sources
 * will overwrite property assignments of previous sources. If a callback is
 * provided it will be executed to produce the merged values of the destination
 * and source properties. If the callback returns `undefined` merging will
 * be handled by the method instead. The callback is bound to `thisArg` and
 * invoked with two arguments; (objectValue, sourceValue).
 *
 * @static
 * @memberOf _
 * @category Objects
 * @param {Object} object The destination object.
 * @param {...Object} [source] The source objects.
 * @param {Function} [callback] The function to customize merging properties.
 * @param {*} [thisArg] The `this` binding of `callback`.
 * @returns {Object} Returns the destination object.
 * @example
 *
 * var names = {
 *   'characters': [
 *     { 'name': 'barney' },
 *     { 'name': 'fred' }
 *   ]
