Some simple but practical math utilities

- findprimes no longer uses OpenMP. It now uses POSIX threads, minimum of 4.

- added Makefile.aocc and Makefile.icc for the AOCC (AMD) and ICC (Intel) compilers.

- primefactors can only handle 32-bit and 64-bit unsigned integers. Run as:

  ```%> ./primefactors ```

  

- primefactorsmp and findprimesmp use GNU MP (GMP) and can handle unsigned integers of

  arbitrary bit width.

- findprimesmp uses POSIX threads, minimum of 4.

- If you run `findprimesmp -h` or `primefactorsmp -h` it will show you all the command

line options:

  

  ```

  %> ./primefactorsmp -h

  Usage: primefactorsmp -b  

  %> ./findprimesmp -h

  Usage: findprimesmp -s  (default 18446744073709551615)

                      -e 

       [ -b  (default 128)]

       [ -T  (default 4)]

       [ -f  (default stdout)]

       [ -p (print header at the top)]

       [ -t (print prime discovery time)]

  ```
