-- | The first command line argument specifies which function to run. If given \"4\" it runs 'uniqNPoeticalG norm4', otherwise 'uniqNPoeticalG norm5'. 
-- The second command line argument (by default is considered equal to 10::Int) is an 'Int' number of the needed printed variants. The next 7 
-- are treated as the Ukrainian words to be ordered accordingly to the norm. For more information, please, refer to the documentation for the abovementioned 
-- functions. 
-- 
-- Afterwards, you can generate a sounding using 'workWithInput' in the \".wav\" format.
