Hey,

first of all I wanted to say how great scriptographer is. thanks a lot for the work, its incredible!
the problem Im facing is, that the tool gardener 2.0 doesnt exactly do what it is supposed to...
I draw an object as told in the instructions, then mark it and draw a path with the gardener tool. but there is nothing showing up, and the console gives me an error saying:

ReferenceError: "mainLayer" is not defined.
at /scripts/gardener2.0.js:360 (getTopLevelObjects)
at /scripts/gardener2.0.js:238 (onMouseDown)

I hope someone can help me with this issue.
Thanks so much,
Christoph
