Current implementation:

float _maxDispersalDistance(float height) {
     float constant = 0.921;
     return RandUniFloatRange(0, 2 * constant * height, &dispersal_rng);
}

Proposed implementation:

float _maxDispersalDistance(float height) {
    float constant = 8.337;
    return RandUniFloatRange(0, 2 * constant * (height/100), &dispersal_rng);
}

Calculation of rate of dispersal now based on maximum height, instead…
deb44ad 
… of actual height of the largest individual, issue #507

- fixed error on line 21
- function is now based on maxHeight instead of height (which is the height of the largest established individual)
- updated equation to ensure order of operations
