I would like to make a split with lua to values separated with ','. For example:

```
  names="surname1 surname11, Name1,surname2, Name2,surname3, Name3, Name33"

```

and get:

```
 surname1 surname11, Name1
 surname2, Name2
 surname3, Name3, Name33

```

only when there isn't space or blanck on both sides of ',' should separate it.

Best regards!
