* @example
|
* var object1 = {

* propOne : 1,
|
* propTwo : {
|
* value1 : 10
|
* }

* var object2 = {

* // propOne : 1,
|
* // propTwo : {
|
* // value1 : 10
|
* // }
|
* // }
|
*
|
* @param {Object} [object1] The first object to merge.
|
* @param {Object} [object2] The second object to merge.
|
* @param {Boolean} [deep=false] Perform a recursive merge.
|
* @returns {Object} The combined object containing all properties from both objects.
