What we claim as our invention is: 1. A pipeline tool for use within a pipeline comprising: a tool body with an internal flow bore; a swellable component disposed about the tool body; and a temporary seal disposed internally of the flow bore. 2. The pipeline tool of claim 1 wherein the tool body further comprises a flared portion. 3. The pipeline tool of claim 1 wherein the tool body is flexible, corrugated, or both. 4. The pipeline tool of claim 1 wherein the tool body comprises a metal alloy. 5. The pipeline tool of claim 1 further comprising a tracking device attached to the tool body. 6. The pipeline tool of claim 5 wherein the tracking device comprises a mechanical fixture. 7. The pipeline tool of claim 5 wherein the tracking device comprises an emitter that emits a signal that can be tracked. 8. The pipeline tool of claim 7 wherein the emitter comprises a magnet, a radioactive isotope, an electronic transmitter, an acoustic transmitter, an ultrasonic transmitter, or a combination thereof. 9. The pipeline tool of claim 1 further comprising a plurality of guide cups attached to the tool body that engage the pipeline when the tool is disposed therein. 10. The pipeline tool of claim 1 wherein the swellable component comprises a material that expands when exposed to a fluid within the pipeline. 11. The pipeline tool of claim 10 wherein the swellable component comprises a core portion. 12. The pipeline tool of claim 11 wherein the core portion comprises an elastic polymer. 13. The pipeline tool of claim 12 wherein the elastic polymer is selected from the group consisting of EPDM, styrene-butadiene rubber, natural rubber, ethylene-propylene monomer rubber, ethylene-vinyl acetate rubber, hydrogenated acrylonitrile-butadiene rubber, acrylonitrile-butadiene rubber, isoprene rubber, chloroprene rubber and polynorboruene. 14. The pipeline tool of claim 11 wherein the core portion comprises a rubber mechanically mixed with a polymer selected from the group consisting of polyvinylchloride, methyl methacrylate, acrylonitrile, and ethylacetate. 15. The pipeline tool of claim 11 wherein the core portion comprises hydrogen dichromat mixed into a compound of glycerol, diethylene glycol, and polycrylamide. 16. The pipeline tool of claim 10 wherein the swellable component further comprises a membrane portion surrounding the core portion. 17. The pipeline tool of claim 16 wherein the fluid permeates the membrane portion more slowly than the core portion. 18. The pipeline tool of claim 16 wherein the membrane portion comprises a rubber. 19. The pipeline tool of claim 18 wherein the rubber is selected from the group consisting of acrylonitrile, hydrogenated nitrile, chloroprene, ethylene vinylacetate rubber, silicone, ethylene propylene diene monomer, butyl, chlorosulphonated polyethylene, polyurethane, ACM, and BIMS. 20. The pipeline tool of claim 16 wherein the swellable component further comprises a reinforcement to the membrane portion. 21. The pipeline tool of claim 1 wherein the temporary seal is selectively disengagable. 22. The pipeline tool of claim 21 wherein the temporary seal comprises a rupture disc. 23. The pipeline tool of claim 1 wherein the temporary seal may be selectively engaged or disengaged. 24. The pipeline tool of claim 23 wherein the temporary seal comprises an electromechanical valve. 25. The pipeline tool of claim 23 wherein the temporary seal may be selectively engaged or disengaged via temperature, a magnetic signal, a pressure signal, an electronic signal, an electromagnetic signal, a timer, an acoustic signal, an ultrasonic signal or a combination thereof. 26. The pipeline tool of claim 1 further comprising a permanent device disposed internally of the flow bore. 27. The pipeline tool of claim 26 wherein the permanent device comprises a valve or a pump.
