### Simulations of classical particles in billiards.
1. *global_particles.c*: global variables and parameters
2. *sub_part_billiard.c*: drawing/computation routines common to particle_billiard and drop_billiard
2. *sub_part_billiard.c*: drawing/computation routines common to `particle_billiard` and `drop_billiard`
3. *particle_billiard.c*: simulation of a collection of non-interacting particles in a billiard
4. *drop_billiard.c*: simulation of an expanding front of particles

- Many laptops claim to have 4 cores, but two of those are virtual. OMP acceleration may be more effective after executing
export OMP_NUM_THREADS=2
`export OMP_NUM_THREADS=2`
in the shell before running the program
