Subject: [PATCH] Add ability to manually stop a timer

This way I can have multiple timers in a given scope that measure different things without super awkward `using`s that end up scoping out variables that I need access to later. The timings get printed in reverse order, of course, but the conveniences provided outweight that minor flaw.
