Created for Ulla Puggaard's "Kingdom of Weeds" - sonifying the leaves from weeds.
- Trace a leaf in black so that it resembles a waveform, use this file as input.
- Get distance in pixels from zero-crossing to amplitude height of the black outline image file using the leaf_tracer.pde script.
- Store the array of distances to be used to write a .wav file from the image
