示例1: autoExpand

/** Checks give TreePath for the last node, and if it ends with a node with just one child,
* it keeps expanding further.
* Current implementation expands through the first child that is not leaf. To more correctly
* fulfil expected semantics in case maxChildToExpand is > 1, it should expand all paths through
* all children.
*
* @param tree
* @param path
* @param maxChildToExpand
