Examples of FocusedRange

org.waveprotocol.wave.model.document.util.FocusedRange
Similar to a {@link Range}, except it is not canonicalised to have a start <= end. Instead, it has an "anchor" and a "focus", which do not have ordering constraints Start and end are also provided for a canonicalised view. @author danilatos@google.com (Daniel Danilatos)
