- !CharacterBlock commentStamp: '<historical>' prior: 0!
- My instances contain information about displayed characters. They are used to return the results of methods:
  Paragraph characterBlockAtPoint: aPoint and
  Paragraph characterBlockForIndex: stringIndex.
+ Any recomposition or movement of a Paragraph can make the information I store stale.
