org.das2.util.filesystem.GitHubFileSystem

GitHubFileSystem allows GitHub directories to be mounted directly, even though it is not a conventional filesystem with files residing in folders. For example, the file resource README.md found in https://github.com/autoplot/scripts/ is downloaded from https://github.com/autoplot/scripts/blob/master/README.md, with "blob/master/" added to the URL. Likewise directory "demos" is found under "tree/master/". GitHub also introduced a new problem, where dates cannot be used for evaluating file freshness. ETags are now supported in WebFileSystem to provide this functionality. Note, GitHub is slow to update the raw view, so five minutes may pass before a pushed change is visible. See https://sourceforge.net/p/autoplot/bugs/2203/ . This can be resolved by maintaining a local clone of the repo.
