Local source content feature implemented in latest release?

[tcatapano]

I see this feature documented in the wiki here:

https://github.com/sgsinclair/VoyantServer/wiki/Using-Local-Source-Content

I've followed the instructions by adding localSource and input lines into server-settings.txt but it does not seem to work. The log says: A corpus was specified but does not exist, could not be migrated and could not be recreated when I use a url ending with ?corpus=[localSource]

I hope this is implemented and that I'm just getting something wrong. I have a corpus with content which is revised somewhat frequently and would like to update the corpus by refreshing with local files rather than by uploading.
