With the aim of moving towards immutable objects, node shouldn't have
dynamic names. I've not found a use for them in my own projects.

Node.getData(): nodes may be empty so return an Optional
...
Most tests used Node::getData as a name supplier for test fixtures.
In some cases these were not needed and have been removed. In others, where
there are used, they have been updated to get the content of the Optional.
If the Optional happens to be empty, which it shouldn't be in those cases,
then an error will occur and the test will, correctly, fail.

NodeItem.insertInPath(): use setData() to when target is already in tree
...
Where an empty node is already found in the tree where we want to insert
a node, use the setData() method to place the data. This replaces the
previous process of attempting to swapping in the new node.

Node.getName(): generated each time called when using a name supplier
...
Previously the name was set when the node was created and only a call to
setName() would have changed it.
isNamed() uses the generated name, so this may change if the generated name
is even null or the empty string.

Node: add {get,find}ChildNamed() methods
...
Both methods look for a child with the given name as an immediate child of
the current node.
findChildNamed:
Will return an Optional containing the found node or empty.
getChildNames:
Is more insistent and will return the found node itself. If a node by that
name is not found, then a NodeException will be thrown.

Node: may have names and a functional name supplier
...
Names, where present, must be unique for each parent.
Node:
* String getName()
* void setName(String name)
* boolean isNamed()
NodeItem - replaces all constructor:
* (data)
* (data, name)
* (data, nameSupplier)
* (data, parent)
* (data, nameSupplier, parent)
The name supplier takes a node and generates a string at the time the node
is constructed. The root node has a default name supplier that returns null
which means that the node is considered unnamed. Other nodes may provide
their own name supplier that would be used be new nodes created within
their subtree.
