that removeChild(Node*), removeChild(uint) and equivilant Geode methods are now inline methods, not designed to be overriden, and seperated out the multiple remove method to be called removeChildren(uint, uint) which is now the only virtual method. There removeChildren is now the method to override in subclasses. This reorganisation requires some call code to be rename removeChild usage to removeChildren.
