exportValue(&$submitValues, $assoc = false)   X-Ref
As usual, to get the group's value we access its elements and call
their exportValue() methods


_createElements()   X-Ref
Creates the group's elements.

This should be overriden by child classes that need to create their
elements. The method will be called automatically when needed, calling
it from the constructor is discouraged as the constructor is usually
called _twice_ on element creation, first time with _no_ parameters.


_createElementsIfNotExist()   X-Ref
A wrapper around _createElements()

This method calls _createElements() if the group's _elements array
is empty. It also performs some updates, e.g. freezes the created
elements if the group is already frozen.
