Grasshopper + Galapogos: finding the shortest path and least slope on a topography

Tutorial shows how to use Galapogos to use multiple fitness functions to determine the shortest path with least slope across a topography. Tutorial uses lists to cull items and reinsert items to make use of the gene pool component from Galaopgos. Also shows a simple mathematical approach to determining the slope along the path using deconstruct points and creating a simple expression. The path is visualized using a gradient highlighting the slope analysis.
