Taking inspiration from the schedlat script, I made a script for tracking scheduler latency system-wide, rather than for a specific process. I also display the latency values in µs to the user (I used this for plotting latency over time). This turned out to be rather useful for me at work.

While finishing it up I noticed issue #14, so implemented the simple version of the fix for that (using TID instead of PID with no aggregation) and it seems to work.

Let me know if you want me to merge schedlatsys and schedlat into one script (e.g. it could use a -a flag for system-wide mode). Note that I calculate %LAT slightly differently in schedlatsys.

Please let me know if I've missed anything, I'm still fairly new to this area.
