Little real documentation is needed.

The RichEdit property allows the developer to quickly
associate the Ruler with a RichEdit, and all
adjustments to the ruler settings at run-time will
automatically adjust the rich edit accordingly.

The Update method is called to adjust the 
TRuler settings to reflect the status of the
RichEdit where the cursor is.
