[FreezePhoenix]

Lets just say that this might help a little?

@fabiocaccamo This PR adds the Array.zip and Array.unzip methods you were going to add.

Hi,
I appreciate your support but your PR is not ok for the following reasons:

• as you can see, the whole lib is written in es5
• your ArrayUtil.zip and ArrayUtil.unzip code is not clear, there are a lot of function calls, please check my implementation, it's very simple :)
• your ObjectUtil.clone implementation doesn't clone nested objects and arrays.

By the way, I just published this lib and I'm writing tests now, many things could change in the short period...

Hi,
Thank you for your constructive response,
As you have noticed, ObjectUtil.clone does not clone nested objects and arrays. That is called deep-cloning. If you were to implement such a method, it would be ObjectUtil.deepClone or ObjecUtils.cloneDeep.

As for the ArrayUtil.zip and ArrayUtil.unzip I can fix that.

@fabiocaccamo I would like this PR to be reopened. The operations added in this PR are not 'simple' nor is there a 'best' way to do them.
