CALCULATE{"formula"} -- handle spreadsheet calculations outside tables

• The %CALCULATE{formula}% variable is handled by the SpreadSheetPlugin. Over 100 functions are available, such as $ABS(), $EXACT(), $EXISTS(), $GET()/$SET(), $IF(), $LOG(), $LOWER(), $PERCENTILE(), $TIME(), $VALUE().
• Syntax: %CALC{formula}%
• Examples:
  • %CALC{$EXISTS(Web.SomeTopic)}% returns 1 if the topic exists
  • %CALC{$UPPER(Collaboration)}% returns COLLABORATION
• Note: The CALCULATE variable is handled inside-out & left-to-right like ordinary TWiki variables, but it does not support functions that refer to table cells, such as $LEFT() or $T(). Use CALC instead.
