Fortran 2003 (initial implementation)

Fortran - read file in and map nodes successfully

Complete but buggy

Doesn't crash, but wrong length

  Gives length of 2147483637

Cleanup

Fixed - now runs with correct distance

Also some fixes to comply with 2003 standard.

Fortran makefile and formatting

Outputs time as integer instead of as float (no decimal).
