This section isn't done (I need to find the correct selenium jar to run). Feel
free to ignore this file for now.

maybe require it to be downloaded to a particular path relative to test.dart?

(Another idea: I wonder if we can get some things pre-installed on the build
bots on their special drive.)

Yes, I will have it downloaded in a particular location, the issue here is I
need to determine what version the user is running
selenium-server-standalone-2.15 or 2.20, etc because my setup script downloads
whatever is latest from the repo.
