Methods:

. Interact - user interactions: deform or initiate simulation

. ModifyMeshGauss - applies a Gaussian disturbance to the mesh

. RunStormwaterModel

. QuickSortTriangles - from highest to lowest elevation

. RouteRunoff

. EvaluateFacingNeighbors - determines the flow path, route flow

. FindNextLowestNeighbor - find the lowest elevation along the flow path.
