Flatten Graft & Simplify in Grasshopper

[@f7oor]

Finally a simple explanation of lists. Thanks!

THIS LESSON IS the central key of understanding grasshopper 3D. This provides everything about bijection, surjection and injection of functions. It's all about the data tree, the manipulation of lists, the data matching and how data flows in our grasshopper visual scripting definition.
I have three years intensely using Grasshopper 3D. This is THE main event of the program. Grasshopper IS a platform that allows simulation, modeling, logic, data structure and pipelining in one software LINKING other softwares for drawing and modeling.
