 This is a tiny Modern Fortran library for handling prime numbers. 
-The base code was spun off the FRESCO CFD code, while additional functions are modern Fortran ports of codes from [Michal Forisek](https://people.ksp.sk/~misof/primes/), [David Deley](https://daviddeley.com/programming/code/primes.htm) and [Primes.jl]([https://github.com/](https://github.com/JuliaMath/Primes.jl).
