Detailed Description

QgsPropertyKey node.

Can, itself, contain QgsPropertyKeys and QgsPropertyValues.

The internal QHash, mProperties, maps key names to their respective QgsPropertyValue or next QgsPropertyKey in the key name sequence. The key with the current name should contain its QgsPropertyValue.

E.g., given the key sequence "/foo/bar", "foo" will have a corresponding QgsPropertyKey with a name "foo". It will contain an element in its mProperties that maps to "bar", which is another QgsPropertyKey. The "bar" QgsPropertyKey will, in turn, have an element that maps to itself, i.e. "bar", that will contain a QgsPropertyValue.
