-- User configuration:
--
-- Standardization
-- Standardization will
--    force upper
--    remove noise characters
--    optionally remove noise words
-- remove noise characters:
--   standardize uses translate to remove noise characters.
--   modify std_translateFrom and std_translateTo to change the
--   translation. Note that translate requires at least one one
--   character in each string to operate. The default values translate
--   '1' to '1' to accomodate this requirement.
--
-- Remove noise words
--   if noise_words is not null, any words in noise_words will be 
--   removed from the standardized string or the standardized tokens.
--   Use may add words to be removed by adding the space delimited words
--   to noise_words.

-- Firm rule noise words
-- The firm rule noise words may be modified in Firm_opt.noise_words.

-- Token standardization
--   Firm, partial_name, abbreviation, and acronym match rules break the match 
--   attribute into standardized tokens. The noise characters are removed from
--   through the translation strings tok_std_translateFrom and tok_std_translateTo.
--   Typically these translation strings will be identical to std_translateFrom and
--   std_translateTo with the exception that the space character should not be 
--   translated out.

-- Mrs match
--  The mrs match allows customized name matching based on the 'Mrs' prename.
--  The prename denoting female, married for the english is 'MRS'. Additional
--  prenames may be added to this list by adding space delimited names to 
--  mrs_prenames.
