1D and 3D Zig shock physics examples
To try the 1D:
% zig build-exe -OReleaseFast 1D/shock.zig
% ./shock >& ultra
% gnuplot
gnuplot> plot "ultra"
gnuplot> exit
%
These are perfect test cases to resolve the following Zig issue, since all numerics are centralized to a few lines.
==============================================
I will accept pull requests that:
(1) Make better use of Zig language features while keeping the source code approximately the same size or smaller.
** AND **
(2) Have performance that is exactly as fast or faster than the version being replaced, definitely for the ReleaseFast build of the code, and maybe also for the Debug build.
