Simple camera path animation

I am a Rhino 3D modeller and would like to do some basic fly-throughs .
The standard animation tools within Rhino 6.0 are very clunky and have
no “ease in /ease out” speed controls on the camera and target paths.
I tried loading “Horster” for Grasshopper, but I got an
“unrecognized objects” warning (Set camera, Animate Camera, Get Camera).
Does anyone have a basic camera / target animation Grasshopper file that I
can use ?


For that I use Heteroptera plugin

I have very little experience with Grasshopper,
I have managed to download and install the Heteroptera plugin,
How do I use it ?
Can you show me a basic example of how to move a camera and a camera target along two polylines with control over each ?
