/**
 * This recursive method will remove the given node and all nodes that
 * are reachable from it from their parents based on the graph given.
 * <p>
 * package private for testing.
 * 
 * @param nodeToRemove
 *            The node to remove from its parents. The nodes reachable
 *            from this node based on the given graph will also be
 *            removed from their parents.
 * @param graph
 *            The graph that will decide what objects are adjacent to
 *            this node. As this method is being used for removing a
 *            {@link WabitObject} and its dependencies from the tree
 *            this graph should contain the {@link WabitObject} being
 *            removed by the action and all of the {@link WabitObject}s
 *            depending on this object and the dependent object's
 *            dependencies.
 * @return true if the node and its descendants were successful. False
 *         otherwise.
 * @throws ObjectDependentException
 *             Thrown if the node that was being removed is still
 *             dependent on other objects existing. This suggests that
 *             there is a problem in the graph given that should connect
 *             all of the objects to their dependencies.
 * @throws IllegalArgumentException
 *             Thrown if a node being removed is not a child of its
 *             parent. This suggests there is something wrong with the
 *             parent/child relationships in the workspace.
