A node can be made active in two ways.
Calling _#activate()_ makes the receiver the active child of its parent node, but does not otherwise disturb the rest of the tree.
Calling _#activateBranch()_ on the other hand effectively the same as:
```java

void activateBranch() {
activate();
if(getParent() != null) getParent().activateBranch();
}
```

It makes the receiver the active child of its parent, and then recursively calls _#activateBranch()_ on its parent.
