Novice user here - I am trying to create a unique space (a neuron) that has
three distinct areas (cell body, axon, and axon terminal). I can only seem
to create a map but I was hoping there was some guidance on how to model
the distinct shapes of all three bodies (sphere/circle, tube/rectangle,
rhizoidal respectively). I need to also be able to specify where certain
turtles spawn, move etc.
