A library of basic functionality needed for
number-theoretic calculations. The aim of this library
is to provide efficient implementations of the functions.
Primes and related things (totients, factorisation),
powers (integer roots and tests, modular exponentiation),
Note: Requires GHC >= 6.12 with the integer-gmp package
for efficiency. Portability is on the to-do list (with
low priority, however).
