Description

I tried here to change the output of delineate() from a list to an S3 object of class delineation and use that to create a plot() method. Now, plot() is not that elegant, nor is it very customizable, but it provides a quick way to the user to examine the output of delineate().

I would also consider this in the context of #262, following your suggestion to refactor delineate(). If data retrieval is moved out from delineate(), then the plot method proposed here needs to be rethought as well. I do think we should move forward with #262, so I am okay with adjusting or dropping this after that.
