function whole stringToFind, sourceText
--| Based on a  script by Sakari Ruoho <sakari.ruoho at academica.com>
--| Tests  for a whole word or phrase in a variable. Returns TRUE or FALSE
--|  Handles single punctuation and hyphenated words.
--| Fails with  unbalanced double punctuation (brackets, quotes etc).
--| Fails if the  string to find is punctuation only
--| Fails with leading  punctuation
--| Does not support multiple-line matching (ignores  ends-of-line)
