/**
@brief A container for static variables defined in Templates.
This class is only relevant to Template tag authors.
When processing a template tag in a AbstractNodeFactory implementation, it will sometimes make sense
to process arguments to the tag as Grantlee::Variables. Note that usually they should be processed as
FilterExpression objects instead.
Arguments to the tag can be used to construct Variables, which may then be resolved into the objects they
represent in the given Context in the render stage.
