Boid Flocking Simulation
Andrew Lee
A flocking simulation built in Rust with ggez

USAGE:
    boidflock.exe [OPTIONS]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
        --seed 
            Seed to determine initial positions and random rotations applied to boids. This make the simulation
            deterministic. If set to default 0, the seed will be randomly generated : u64 [default: 0]
        --boid-count                             Count of boids to simulate : [0, INF) [default: 2000]
        --coherence 
            Coefficient for boid aiming for center of local neighbor mass : [0, 1] [default: 0.035]

        --separation 
            Coefficient for boid avoidance within AVOID_RANGE : [0, 1] [default: 0.25]

        --alignment 
            Coefficient for boid alignment of velocity within SIGHT_RANGE : [0, 1] [default: 0.75]

        --avoid-range 
            Pixel distance for a boid to avoid others in line of sight : [0, INF) [default: 21.]

        --visual-range 
            Pixel sight distance for each boid : [0, INF) [default: 80.]

        --sight-angle 
            Sight pie-slice angle for each boid in radians : [0, 2*PI] [default: 2.3]

        --sight-samples 
            Samples to take get cells within sight angle range : [1, INF) [default: 3]

        --max-rand-rotate 
            Max random velocity rotation angle for boids : [0, 2*PI] [default: 0.3]

        --min-veloc 
            Minimum boid velocity in pixels : [0, MAX_VELOC] [default: 3.]

        --max-veloc 
            Maximum boid velocity in pixels : [MIN_VELOC, INF) [default: 5.]

        --cur-cell-neighbors 
            Maximum number of boid neighbors within current sight range cell to consider for calculations : [0,
            BOID_COUNT] [default: 30]
        --forward-cell-neighbors 
            Number of boids in sight range in sight range cell ahead to consider : [0, BOID_COUNT] [default: 10]

        --edge-turn-margin 
            Pixel distance from screen edge for boids to turn away from to stay on screen : [0, INF) [default: 25.]

        --edge-turn-factor 
            Coefficient to turn away from screen edges : [0, 1] [default: 0.2]

        --img-scale                               Scale for boid image : [0, INF) [default: 0.32]
        --zoom-scale 
            Scale to zoom. Above 1 zooms in, below 1 down to 0 zooms out : [0, INF) [default: 0.8]
