I've been racking my brains trying to think up more hints, but it 
can't be done, because this is so easy that even the oblique 
hints that have already appeared come a little too close to the 
knuckle.

Instead, then, here are a known plaintext (all one line, with one 
newline at the end) and its corresponding ciphertext:

To be, or not to be, that is the question: whether 'tis nobler in 
the mind to suffer the slings and arrows of outrageous fortune or 
to take arms against a sea of troubles, and by opposing end them. 
To die, to sleep, no more; and by a sleep to say we end the 
heartache, and the thousand natural shocks that flesh is heir to; 
'tis a consummation devoutly to be wish'd.
