TEMP-TABLE|BUFFER [name] is not used

Rule "tableusage" is a rule that identifies unused TEMP-TABLE, WORK-TABLE, and BUFFER definitions.

Notes:

The author, Igor Natanzon says:

• Line number for the END keyword is not a reliable block indicator (
  ie. END. END. on one line). However, as each block is processed
  separately, I haven't noticed any problems yet. I suspect it should
  not be a problem because procedures, functions, and event triggers
  cannot be nested (or can they??).
• Blocks I consider local for buffer define purpose are PROCEDURE,
  FUNCTION, METHOD, and ON event trigger. Any more? Any other define is
  considered global.
