(Tested on Windows)
Typing "lcm create" with no other arguments creates a directory named [object Object]. Running "lcm server" in this state starts an app that returns 404 for GET /.
The help text makes no mention of the fact that you need an argument to "lcm create".
Fixed by PR #94 and commit 436ee2d. Will be available in Locomotive 0.4.0, when released.
