Plankton meshes in Rhino 6

Hi @DanielPiker,

I have been using plankton meshes in VB in Rhino 5 and it was working perfectly fine. In Rhino 6, though, I cannot get it right.

I guess the syntaxes have maybe changed, for example, .toplanktonmesh! So, I cannot turn a gh_mesh into plankton mesh in the first place.
