Used comma-separated rather than space-separated vector strings in the transformation examples to match the usage in the symCIF dictionary. Clarified that the tranformation-string format separates the point and translational components with a semicolon (all Pp type tags). Clarified that the parent space-group to child transformation applies to the basic space group when the child is incommensurate.
