Null Reference Exceptions

[jamsoft]

I was looking forward to using this but it just seems too bug ridden.

I'm getting null references on the following lines:

var targetChildrenLast = targetChildren[targetChildren.length - 1];

There are other null references and basically though my initial testing it's just too buggy to use. If I make any discoveries or have time I'll attempt a fix and PR.

Thanks. It may not affect the use.
