Update rate of dispersal calculation based on maximum height (HMAX) instead of actual height of the tallest plant

[kpalmqui]

Current implementation:

float _rateOfDispersal(float PMD, float height, float maxDistance) {
       return log(PMD) * height / maxDistance;
 }

Proposed implementation:

float _rateOfDispersal(float PMD, float maxHeight, float maxDistance) {
return (log(PMD) * maxHeight) / maxDistance;
}

… 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

resolved by above.
