Subject: [PATCH] Make intentions a tuple (to denote immutability)

Since the atom intentions are not meant to be mutable
we should make sure that we create the object as a type
which is not mutable. This helps with those looking over
the code to understand its desired usage which is not to
be a mutable collection.
