lib94 attempts to follow the draft standard at <https://corewar.co.uk/standards/icws94.txt>, minus P-space. There are no read/write
limits (or if you prefer, they are the same as the core size). The minimum separation is always 0, and the core size is set at 8000.
To change the core size, change LIB94_CORE_SIZE in include/lib94/lib94.hpp, run make clean, and then run make.
To change the core size, change LIB94_CORE_SIZE in include/lib94/lib94.hpp, run make clean, and then run make. The maximum number of
processes is set at 16000. To change that, change LIB94_MAX_PROCESSES in include/lib94/lib94.hpp, run make clean, and then run make.
