-- Program Tiggrphone.e
--
-- This is to phonetically compare words for parsing or for
-- spell correction use. Or anything else i think of.
-- Both Soundex and Metaphone strip out vowels by default,
-- i believe this is an error, they throw away too much info.
--
-- The problem with *any* scheme to simplify words this way is stymied by
-- words such as:
-- mint/pint cough/bough clove/love cachet/hatchet
-- These pairs, and others like them, can only be resolved
-- by actually knowing the pronunciation.
--
-- entry point is function Tiggrfoneize()
--
-- Recieves theword as "WORD", with no duplicated letters.
-- If you cannot do uppercase, then use "+" as part of the level.
-- We don't handle the first letter, it stays unchanged in all soundex levels.
-- The original Soundex did levels 0,1,2 -- *very* lossy, imo.
--
-- The levels herein are applied in this order: C - U - S - 0 - 4+1 - 3 - 2
-- C = convert "3L33T" IRC chars to base letter, example: "?" becomes "o"
-- U = upcase the word for user, so "word" or "Word" can be recieved
-- S = strip punctuation and duplicate letters
-- 0 = no vowels, or H or W, unless it is the first letter
-- 1 = converts to numeric codes, except for the first letter
-- 2 = chops the result to 4 chars
-- 3 = enhanced Soundex
-- 4 = convert the first letter to numeric code when using level 1
-- returns theword in uppercase and/or numeric codes, as selected
--
-- sendMirc() is because i used mirc as a gui, since there isn't one for Euphoria.
