-// Cgroup models one line from /proc/[pid]/cgroup. Each Cgroup struct describes the the placement of a PID inside a

-// contain all running processes, so the question answerable with a Cgroup struct is 'where is this process in
-// this hierarchy' (where==what path on the specific cgroupfs). By prefixing this path with the mount point of
-// *this specific* hierarchy, you can locate the relevant pseudo-files needed to read/set the data for this PID
