Uses the custom class OPTimer to create an accurate timer that uses background threading

###How to get started

1. Drag the files "OPTimer.h" and "OPTimer.m" into your project (make sure they are COPIED and added to the target).
2. Put '#import "OPTimer.h"' wherever you want to use it.
3. See below.

###How to use OPTimer

// Create the timer like the normal NSTimer
OPTimer* timer = [OPTimer timerWithTimeInterval:0.1f
                                         target:self
                                       selector:@selector(timerHasFired:)
                                       userInfo:nil];


// Start that bad boy up, since it isn't scheduled
[timer startFiring];

You could also use the other class method to create an automatically started timer like so:

[OPTimer scheduledTimerWithTimeInterval:1.0f
                                 target:self
                               selector:@selector(otherTimer:)
                               userInfo:nil];
