What is claimed is: 1. An apparatus for applying a slider to a zippered bag, wherein the slider has a back wall and two cantilevered side walls, the apparatus comprising a bag machine configured to move a zippered bag in a substantially linear direction to present the zippered bag to a slider pusher, a slider sorter configured to align the slider in a desired orientation, a track configured to maintain the alignment of the slider while transporting the slider away from the slider sorter, a slider pusher configured to receive the slider from the track and move the slider substantially perpendicular to the substantially linear direction and toward the zippered bag, a splitter comprising separate blades configured to spread the cantilevered side walls of the slider and allow the back wall to pass between the blades as the slider is moved into engagement with the zippered bag, and a bag machine configured to present the zippered bag to the slider pusher, the apparatus being configured to apply the slider while the zippered bag is in motion. 2. The apparatus of claim 1, wherein the splitter is moveable with respect to the bag and zipper and configured to fit between and wedge open the cantilevered side walls of the slider prior to the slider's engagement with the zippered bag. 3. The apparatus of claim 1, wherein the slider is oriented in a selected one of two directions when it is received by the slider pusher. 4. The apparatus of claim 3, wherein the slider pusher includes a slider application head having a front lip and a rear wall, the front lip and rear wall cooperating to define a slider-receiving space there between. 5. The apparatus of claim 4, wherein the back wall of the slider is ramped in order to facilitate finger-actuation of the slider, and the rear wall of the slider application head is ramped an equal degree in the opposite direction in order to accommodate the slider. 6. The apparatus of claim 5, wherein the rear wall of the slider application head comprises an interchangeable ramped surface for accommodating sliders oriented in either direction. 7. The apparatus of claim 1, further comprising a bag guide for laterally retaining the bag in place when the slider is applied to the bag. 8. The apparatus of claim 1, wherein the slider has a back wall connecting two cantilevered side walls with teeth on the ends of each side wall and the slider pusher is configured to move the slider toward the zippered bag so that all of the teeth pass over the zipper substantially simultaneously. 9. An apparatus for applying a slider to a zippered bag, the apparatus comprising a bag machine configured to transport the zippered bag, and a slider applicator configured to apply a slider to the zippered bag as it is transported by the bag machine, the slider applicator comprising an upper portion above the bag machine and a lower portion below the bag machine, the slider applicator comprising a slider sorter configured to align the slider in a desired orientation, a track configured to maintain the alignment of the slider while transporting the slider away from the slider sorter, a slider pusher configured to receive the slider from the track and move the slider toward the zippered bag, an actuator coupled to the slider pusher and configured to move the slider pusher in response to signals from a component on the bag machine, a splitter comprising separate blades, the splitter being moveable with respect to the bag and zipper and configured to fit between and wedge open the cantilevered side walls of the slider prior to the slider's engagement with the zippered bag, the splitter being configured to allow the back wall of the slider to pass between the blades as the slider is being applied to the bag, the actuator being mounted on the lower portion of the slider applicator. 10. The apparatus of claim 9, further comprising a bag guide mounted to the upper portion, the bag guide being configured to permit movement of the bag and simultaneously control lateral movement of the bag away from the slider applicator. 11. An apparatus for applying a slider to a zippered bag on a bag machine, the bag machine substantially defining a plane, the slider having a back wall connecting two cantilevered side walls with teeth on the ends of each side wall and the zippered bag having a zipper, the apparatus comprising a transportable frame capable of being moved between the bag machine and a second bag machine, a slider sorter coupled to the frame, the slider sorter being configured to align the slider in a desired orientation, a slider pusher coupled to the slider sorter and configured to move the slider toward the zippered bag so that all of the teeth pass over the zipper substantially simultaneously, the slider pusher being actuated by an actuator positioned below the plane defined by the bag machine, and splitter blades configured to spread the cantilevered side walls of the slider prior to the slider's engagement with the zippered bag and allow the back wall to pass between the blades as the slider is being applied to the bag. 12. A method of applying a slider to a bag having a zipper wherein the slider has a back wall and two cantilevered side walls, the method comprising the steps of aligning the slider in a predetermined orientation, presenting the slider to a slider pusher, moving the zippered bag in a substantially linear direction in front of the slider pusher, and moving the slider pusher substantially perpendicular to the substantially linear direction toward the bag and applying the slider to the zipper while the bag is in motion, with the slider pusher moving toward the bag so that the slider is caused to contact splitter blades thereby causing cantilevered side walls of the slider to spread apart prior to engaging the zipper and allowing the back wall of the slider to pass between the blades as the slider is being applied to the bag. 13. The method of claim 12, wherein the splitter moves into position adjacent the bag and zipper, wedges open the cantilevered side walls of the slider prior to the slider's engagement with the zippered bag and moves away from the bag and zipper. 14. The method of claim 13, wherein the supported for movement on top of a bag machine and the linear servo motor is positioned below a plane defined by the bag machine. 15. The method of claim 12, wherein the slider has a back wall and two cantilevered side walls, and the slider applying step includes moving the slider into contact with a splitter such that the splitter causes the cantilevered side walls to spread apart enough to pass over the zipper. 16. The method of claim 12, wherein the splitter is actuated by a linear servo motor independently of the slider pusher. 17. The method of claim 15, wherein the splitter has a first non-spreading position, and a second slider-spreading position wherein the splitter is positioned adjacent the moving bag. 18. The apparatus of claim 11, wherein the splitter is moveable with respect to the bag and zipper and configured to fit between and wedge open the cantilevered side walls of the slider prior to the slider's engagement with the zippered bag.
