I clarified the root node and made a new variable to hold the node for
the bar folder.
```java
// bar is a folder created through the webdav interface.
Node root,folder;
root = session.getRootNode();
folder = root.getNode("bar");
// fails here
Node child = folder.addNode("grade.png");
```
Error message is the following
"No child node definition for grade.png found in node /bar"

"There are two ways of constructing a software design. One way is to
make it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies."
