checkUUIDInfoBox

private boolean checkUUIDInfoBox(Node node,

Check whether the child with a name childName exists. This method is designed because UUID info box may have many instances. So if one of its sub-box is inserted into the tree, an empty slut for this sub-box has to be find or created to avoid one UUID info box has duplicated sub-boxes. The users have to guarantee each UUID info box has all the sub-boxes.
