api

#### timer = every(ms[, installTimer, uninstallTimer, now])

create an event emitter that emits every ms.

optionally provide your own install / uninstall functions for timers.

install functions are expected to return a handle which will then be given to the
uninstall function when the timer is destroyed.

you may also provide your own now function -- it defaults to Date.now().

#### timer.paused() -> Boolean

returns whether or not the timer is paused.

#### timer.pause()

pauses the timer. the timer will not emit events while paused.

#### timer.resume()

resumes the timer. the timer will start emitting events again.
it will not emit the difference between pause and resume` on the next step.

#### timer.rate() -> currentRateMS

emit the current rate in milliseconds.

#### timer.rate(rate) -> currentRateMS

set the current rate in milliseconds.

#### timer.destroy()

uninstalls the timer function.
