Re: #25 (acrostic puzzle generator)

One quibble - this set of rules is tighter than what most puzzle
magazines use.  In most magazines, there is only a number under
each letter in the quotation, and that same number may occur
under letters in more than one of the singlew word answers
(which is why there is no letter to index into the word list).
So, the total number of letters in the words can be greater
than the total number of letters in the quotation, and there
is an additional form of feedback in solving the puzzle.
(I.e. when you guess an answer to one word, you check whether
any of the numbers match the number under a letter in other
words and transfer the letter to those locations as well as
to the quotation.)

That gives a lot more flexibility when choosing the word list,
since you aren't ending up looking for a true anagram of the
last few letters and having to backtrack when there isn't such
an anagram.  This makes it easier for a human designer to come
up with a nicely balanced word list; and it gives a computer
program more rope for hasnging itself with infinite recursion.
