efficient, purely functional generation of prime numbers; profiling libraries

 This Haskell library provides an efficient lazy wheel sieve for prime
 generation inspired by Lazy wheel sieves and spirals of primes by Colin
 Runciman and The Genuine Sieve of Eratosthenes by Melissa O'Neil.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
