What is claimed is: 1. A media bag holder system comprising: a media bag holder having a floor with a sidewall upstanding therefrom and bounding a chamber, the floor having a top surface and an opposing bottom surface, the top surface extending to an inside perimeter edge that encircles an opening

What is claimed is: 1. A media bag holder system comprising: a media bag holder having a floor with a sidewall upstanding therefrom and bounding a chamber, the floor having a top surface and an opposing bottom surface, the top surface extending to an inside perimeter edge that encircles an opening extending through the floor, a support structure being mounted on the bottom surface of the floor and projecting into the opening at a location below the top surface of the floor; and a bottom gate comprising a plate having a top surface and an opposing bottom surface that both extend to an encircling outside perimeter edge, a passage extending through the plate from the top surface to the bottom surface, the plate being lowered down through the chamber and seated on the support structure so as to be disposed within the opening, the bottom gate being slidably movable on the support structure between an unlocked position wherein the bottom gate can be vertically lifted out of the opening so as to pass through the chamber of the media bag holder and a locked position wherein the gate is precluded from being vertically lifted out of the opening. 2. The media bag holder system as recited in claim 1, wherein the passage extending through the plate comprises an elongated slot extending from the outside perimeter edge of the plate toward an interior of the plate, the slot terminating at an inwardly tapered neck opening at the interior of the plate that access a hole extending through the plate. 3. The media bag holder system as recited in claim 1, wherein the top surface of the bottom gate is flush with top surface of the floor when the bottom gate is in the locked positioned within the opening. 4. The media bag holder system as recited in claim 1, further comprising: two or more spaced apart locking slots recessed on the inside perimeter edge of the media bag holder or the outside perimeter edge of the bottom gate; and two or more locking tabs projecting from the other of the inside perimeter edge or the outside perimeter edge, the locking tabs being received within the locking slots. 5. The media bag holder system as recited in claim 4, further comprising a stepped shoulder formed on a portion of the bottom gate or media bag holder bounding one of the locking slots, the stepped shoulder being disposed below one of the locking tabs when the bottom gate is in the locked position. 6. The media bag holder system as recited in claim 1, further comprising a stepped shoulder formed on the perimeter edge of the bottom gate and a locking tab formed on the inside perimeter edge of the media bag holder, the stepped shoulder being disposed below the locking tab when the bottom gate is in the locked position. 7. The media bag holder system as recited in claim 1, wherein the plate has a substantially rectangular configuration and has a second passage extending therethrough, the second passage comprising an elongated second slot extending from the outside perimeter edge of the plate toward an interior of the plate, the second slot terminating at an inwardly tapered second neck opening at the interior of the plate that access a second hole extending through the plate. 8. A media bag holder system comprising: a media bag holder having a floor with a sidewall upstanding therefrom and bounding a chamber, the floor having a top surface and an opposing bottom surface, the top surface extending to an inside perimeter edge that encircles an opening extending through the floor, a support structure being mounted on the bottom surface of the floor and projecting into the opening at a location below the top surface of the floor; and a bottom gate comprising a plate having a top surface and an opposing bottom surface that both extend to an encircling outside perimeter edge, an elongated first slot extending from the outside perimeter edge of the plate toward an interior of the plate, the first slot terminating at an inwardly tapered first neck opening at the interior of the plate that accesses a first hole extending through the plate, the plate being lowered down through the chamber and seated on the support structure so as to be disposed within the opening of the media bag holder. 9. The media bag holder system as recited in claim 8, further comprising a media bag having a tube projecting therefrom, the tube being positioned within the first hole and having an outside diameter that is smaller than the inwardly tapered first neck opening. 10. The media bag holder system as recited in claim 8, further comprising an elongated second slot extending from the outside perimeter edge of the plate toward an interior of the plate, the second slot terminating at an inwardly tapered second neck opening at the interior of the plate that accesses a second hole extending through the plate. 11. The media bag holder system as recited in claim 8, wherein the top surface of the bottom gate is flush with top surface of the floor of the media bag holder. 12. The media bag holder system as recited in claim 8, further comprising a recess formed on the top surface of the plate about the first hole. 13. A method for positioning a media bag comprising: lowering a bottom gate into a chamber of a media bag holder until the gate is supported within an opening extending through a floor of the media bag holder; passing a tube projecting from a media bag through a slot extending through the bottom gate; and sliding the bottom gate horizontally into a locked position within the opening of the media bag holder so that the bottom gate is precluded from being vertically lifted out of the opening while in the locked position. 14. The method as recited in claim 13, wherein the tube is passed through the slot on the bottom gate when the bottom gate is within chamber of the media bag holder. 15. The method as recited in claim 13, wherein the tube is passed through the slot on the bottom gate prior to inserting the bottom gate into the chamber of the media bag holder. 16. The method as recited in claim 13, wherein the bottom gate comprises a plate having a top surface and an opposing bottom surface that both extend to an encircling perimeter edge, the slot extending from the perimeter edge toward an interior of the plate, the slot terminating at an inwardly tapered neck opening at the interior of the plate that access a first hole extending through the plate, the step of passing the tube comprising advancing the tube along the slot and into the hole by passing the tube through the inwardly tapered neck opening, the tube having an outer diameter that is larger than the inwardly tapered neck opening. 17. A method for positioning a media bag comprising: lowering a bottom gate into a chamber of a media bag holder until the gate is supported within an opening extending through a floor of the media bag holder, the bottom gate comprising a plate having a top surface and an opposing bottom surface that both extend to an encircling outside perimeter edge, an elongated first slot terminating at an inwardly tapered first neck opening at the interior of the plate that accesses a first hole extending through the plate; and passing a tube projecting from a media bag along the first slot and into the first hole by passing the tube through the inwardly tapered first neck opening, the tube having an outer diameter that is larger than the inwardly tapered first neck opening. 18. The method as recited in claim 17, wherein the tube is passed along the first slot prior to lowering the bottom gate into the chamber of the media bag holder. 19. The method as recited in claim 17, wherein the tube is passed along the first slot after lowering the bottom gate into the chamber of the media bag holder.
