Add pythonpath programmatically?

[bmcrae]

So, one of the hassles of installing on multiple machines (especially Mac, for me, since I'm not very familiar with the file system and hidden files) is setting the pythonpath so that it includes the circuitscape directory. Wouldn't it be possible to just do this in csgui.py at runtime?

I stumbled across this issue when looking for an answer to this very question. I worked out a solution in the end, and I thought I'd post it here in case others are interested.

Since I'm calling circuitscape from R, I worked out that I can set PYTHONPATH using Sys.setenv in R, and then call circuitscape using system and it works.
