/* 
This is the skeleton of a program to generate free style poetry.


Read it carefully and understand what each function does, and how all
functions work together to generate verses and stanzas.

There is (just) one rule for generating a verse:

verse ==> 'The' adjective noun verb adjective object

Your task is to extend this program to generate better poetry. For
instance, you could add more words to the word lists, add more word
lists (prepositions, interjections, et cetera), add different rules
for creating verses, add rhyme, do not use the same word twice in a
verse, add stanzas with different number of verses, add more stanzas,
et cetera. This are just some examples, use your imagination!!
