Nesting level too deep – recursive dependency

[foxdie]

hi,

Thanks for your job and sorry for my bad english.
A fatal error is thrown when you try to move a child node before or after one of its siblings because they both have the same parent.

Note that It only occurs with php > 5.1 ( i think php 5.2 has changed the way of comparing 2 objects )
You can fix it by replacing :

if( $node == $this )

with :

if( $node === $this )

in the NodeWrapper class.
