Subject: [PATCH] Fix for when JsonNode child is null

This prevents running into NullPointerException when traversable(child) is called while child = null

Here an example of the error it will prevent.


```

Caused by: java.lang.NullPointerException: null
	at jsontotree.Misc.traversable(Misc.java:96)
	at jsontotree.Misc.traverseObject(Misc.java:61)
	at jsontotree.Misc.traverse(Misc.java:44)
	at jsontotree.Misc.traverseArray(Misc.java:84)
	at jsontotree.Misc.traverse(Misc.java:42)
	at jsontotree.Misc.traverseRootObjects(Misc.java:28)
	at jsontotree.actions.ConvertJSONToRootTree.executeAction(ConvertJSONToRootTree.java:52)

```
