Short: "<WIP> mount weed filer to a directory as file system in userspace(FUSE)",
Long: `mount weed filer to userspace.
Pre-requisites:
1) have SeaweedFS master and volume servers running
2) have a "weed filer" running
These 2 requirements can be achieved with one command "weed server -filer=true"
This uses github.com/seaweedfs/fuse, which enables writing FUSE file systems on
Linux, and OS X.
On OS X, it requires OSXFUSE (http://osxfuse.github.com/).
