==== Lazy sequences ====

primes - based on the "naive" implemention described in [1] plus a
small "wheel" which eliminates multiples of 2, 3, 5, and
7 from consideration by incrementing past them. Also inspired
by code from Christophe Grand in [2].

fibs - all the Fibonacci numbers

powers-of-2 - all the powers of 2

==== Lazy sequence functions ====

(partition-all, shuffle moved to clojure.core)
(rand-elt moved to clojure.core/rand-nth)
(rotations, rand-elt moved to seq_utils.clj)
(permutations and combinations moved to combinatorics.clj)
