topline - 0.6-1 main

This is a top-of-the-line logger of CPU usage patterns, designed for
machines with a lot of cores, up to ~140 total hardware threads on an 80
column terminal, more if your terminal is not minimal. Every per-tick
sample is shown abusing Unicode characters to fit within a single line.
.
Disk usage is also shown in a similarly terse per-device way, as %
utilization for reads and writes.
