I claim: 1. A collapsible truck bed cover comprising: (a) a frame; and (b) an outer covering; wherein the frame comprises four primary support bars, four secondary support bars, and four cross bars; wherein two of the primary support bars and two of the secondary support bars are located on each side of the frame; wherein the cross bars connect one side of the frame to the other; wherein on each side of the frame, two of the primary support bars are pivotally connected to each other at one end of each primary support bar, and wherein this is the only point at which the primary support bars are connected to one another; wherein the truck bed cover is installed on a truck bed, wherein the truck bed comprises side rails, and wherein the pivot point at which the two primary support bars are connected to each other is located inside and below the side rails; wherein each primary support bar is connected to a cross bar at the end of the primary support bar that is not connected to the other primary support bar; wherein each secondary support bar is connected to one of the primary support bars at one end of the secondary support bar, and wherein each secondary support bar is perpendicular to the primary support bar to which it is connected; wherein the point at which each secondary support bars connects to a primary support bar is a pivot point; wherein each secondary support bar is connected to a cross bar at the end of the secondary support bar that is not connected to a primary support bar; wherein the secondary support bars are not connected to one another, wherein two of the cross bars connect the four secondary support bars; and wherein two of the cross bars connect the four primary support bars. 2. The collapsible truck bed cover of claim 1, further comprising a torsion spring at each of the four pivot points at which a secondary support bar connects to a primary support bar, wherein the torsion spring biases the secondary support bars toward the primary support bars to facilitate the collapsing of the frame. 3. The collapsible truck bed cover of claim 1, wherein the four primary support bars comprise two front primary support bars and two rear primary support bars, wherein the frame attaches to the truck bed by means of a stationary pivot point on either side of the truck bed, wherein the truck bed cover is installed on a truck bed, wherein the truck bed comprises side rails, and wherein the stationary pivot point is located inside the side rails and on the two rear primary support bars. 4. The collapsible truck bed cover of claim 3, wherein each stationary pivot point comprises a torsion spring that biases one of the rear primary support bars toward one of the front primary support bars to facilitate the collapsing of the frame. 5. The collapsible truck bed cover of claim 1, wherein the point at which the primary support bars are connected to one another is a swinging pivot point, such that when the frame is collapsed, the swinging pivot point moves toward the rear of the vehicle, and when the frame is opened, the swinging pivot point moves toward the front of the vehicle. 6. The collapsible truck bed cover of claim 5, wherein each swinging pivot point comprises a torsion spring that biases the primary support bars toward each other to facilitate the collapsing of the frame. 7. The collapsible truck bed cover of claim 1, wherein when the frame is in a full open position, the angle between each primary support bar and the top of the truck bed is approximately forty-five degrees. 8. The collapsible truck bed cover of claim 1, wherein the truck on which the cover is installed comprises a cab, wherein the cab comprises a rear face, wherein the four primary support bars comprise two front primary support bars and two rear primary support bars, wherein each front primary support bar comprises a top portion, and wherein the top portion of each of the two front primary support bars is curved so that when the frame is fully extended, the top portion of each front primary support bar is roughly longitudinally parallel to the rear face of the cab so as to facilitate folding of the truck bed cover underneath an existing tonneau cover. 9. The collapsible truck bed cover of claim 1, wherein the outer covering is comprised of a flexible material, and wherein the outer covering comprises one or more windows. 10. The collapsible truck bed cover of claim 9, wherein the windows are comprised of transparent vinyl. 11. The collapsible truck bed cover of claim 1, further comprising four straps, wherein the outer covering comprises a top panel, wherein the four cross bars comprise two front cross bars and two rear cross bars, wherein two of the straps connect the two front cross bars and two of the straps connect the two rear cross bars, and wherein the straps lie directly beneath the top panel of the outer covering. 12. The collapsible truck bed cover of claim 1, wherein the outer covering comprises a top panel, and wherein each of the four cross bars is inserted into a sleeve that is sewn onto the underside of the top panel. 13. The collapsible truck bed cover of claim 1, further comprising two straps, wherein the outer covering comprises a top panel, and wherein each strap is attached to the top panel at one end and removably attached to the rear end of the truck bed at the other end. 14. The collapsible truck bed cover of claim 1, further comprising two cords, wherein the outer covering comprises a rear panel, and wherein each cord is attached to the bottom end of the rear panel at one end and removably attached to the rear end of the truck bed at the other end. 15. The collapsible truck bed cover of claim 1, further comprising four zippers, wherein the outer covering comprises a top panel, two side panels, a front panel, and a rear panel, and wherein two of the zippers are situated between the front panel and one of the side panels, and wherein two of the zippers are situated between the rear panel and one of the side panels. 16. The collapsible truck bed cover of claim 1, wherein the outer covering comprises a rear panel, and wherein the rear panel comprises a tailgate cover piece. 17. The collapsible truck bed cover of claim 16, wherein the truck on which the cover is installed comprises a tailgate, and wherein the tailgate cover piece is contoured to fit the shape of the tailgate. 18. The collapsible truck bed cover of claim 1, wherein the truck bed cover is installed on a truck bed, wherein the truck bed comprises side rails, and wherein when the cover is fully collapsed, it fits completely underneath an existing tonneau cover pulled flat over the side rails. 19. The collapsible truck bed cover of claim 1, wherein the truck bed cover is installed on a truck bed, wherein the truck bed comprises side rails, and wherein the entire frame is located inside of the side rails but no part of the frame is located directly on top of the side rails.
