This plugin allows to display command's execution time in a very nonintrusive way.
Timer can be tuned by these two variables:
* `TIMER_PRECISION` allows to control number of decimal places (default `1`)
* `TIMER_FORMAT` allows to adjust display format (default `'/%d'`)
Sample session:
me@here:~$ sleep 1 /1.0s
me@here:~$ sleep 73 /1m13.0s
me@here:~$ TIMER_FORMAT='[%d]'; TIMER_PRECISION=2 [0.00s]
me@here:~$ head -c50 < /dev/urandom | hexdump
