What is claimed is: 1. A trailing edge cap for a blade, said trailing edge cap comprising a body configured to mount on at least two blades, wherein each of the at least two blades has at least one of a differing size and a differing shape, said body at least partially covers an original trailing edge portion of the blade, said body having a body edge portion for forming a new trailing edge portion of the blade when said body is mounted on the blade, said body edge portion having a first thickness defined between a higher pressure side of said body edge portion and a lower pressure side of said body edge portion when said body is mounted on the blade, and the original trailing edge portion of the blade having a second thickness defined between a higher pressure side of the blade and a lower pressure side of the blade, said first thickness less than the second thickness. 2. A trailing edge cap in accordance with claim 1 wherein said body edge portion is configured to mount on the blade such that said body at least partially covers the original trailing edge of the blade, and said body edge portion includes a body edge for forming a new trailing edge of the blade when said body is mounted on the blade. 3. A trailing edge cap in accordance with claim 2 wherein said body edge comprises a curved surface. 4. A trailing edge cap in accordance with claim 2 wherein said body is fabricated from a unitary sheet of material and is creased to form said body edge. 5. A trailing edge cap in accordance with claim 1 wherein said body is fabricated from two separate sheets of material. 6. A trailing edge in accordance with claim 5 wherein said two separate sheets of material are bonded together generally adjacent a body edge of said body edge portion. 7. A trailing edge cap in accordance with claim 1 wherein said body comprises a polymer. 8. A trailing edge cap in accordance with claim 7 wherein said body comprises a polyimide. 9. A trialing edge cap in accordance with claim 1 wherein said body has a body thickness of between about 1 mil and about 100 mils. 10. A trailing edge cap in accordance with claim 1 wherein said body has a modulus of elasticity of between about 0.5 GPa and about 5 GPa. 11. A trailing edge cap for a blade, said trailing edge cap comprising a body configured to mount on the blade such that said body at least partially covers an original trailing edge portion of the blade, said body comprising: a body edge portion for forming a new trailing edge portion of the blade when said body is mounted on the blade, said body edge portion having a first thickness defined between a higher pressure side of said body edge portion and a lower pressure side of said body edge portion when said body is mounted on the blade, the original trailing edge portion of the blade having a second thickness defined between a higher pressure side of the blade and a lower pressure side of the blade, said first thickness less than the second thickness; and at least one of a body thickness of between about 1 mil and about 100 mils, a modulus of elasticity of between about 0.5 GPa and about 5 GPa, and a polymer. 12. A trailing edge cap in accordance with claim 11 wherein said body edge portion is configured to mount on the blade such that said body at least partially covers the original trailing edge portion of the blade, and said body edge portion includes a body edge for forming a new trailing edge of the blade when said body is mounted on the blade. 13. A trailing edge cap in accordance with claim 12 wherein said body edge comprises a curved surface. 14. A trailing edge cap in accordance with claim 11 wherein said body comprises an adhesive for mounting said body on the blade. 15. A blade comprising: a blade body having a leading edge portion and an original trailing edge portion; and a trailing edge cap mounted on said blade body and at least partially covering said original trailing edge portion, said trailing edge cap comprising: a trailing edge cap body comprising a body edge portion having a first thickness defined between a higher pressure side of said body edge portion and a lower pressure side of said body edge portion when said trailing edge cap body is mounted on said blade body, said body edge portion forming a new trailing edge portion of said blade body, said original trailing edge portion of said blade body having a second thickness defined between a higher pressure side of said blade body and a lower pressure side of said blade body, said first thickness less than said second thickness; and at least one of a trailing edge cap body thickness of between about 1 mil and about 100 mils, a modulus of elasticity of between about 0.5 GPa and about 5 GPa, and a polymer. 16. A blade in accordance with claim 15 wherein said original trailing edge portion comprises an original trailing edge, said new trailing edge portion comprises a new trailing edge, and said new trailing edge portion at least partially covers said original trailing edge. 17. A blade in accordance with claim 16 wherein said original trailing edge is formed by an intersection between said higher pressure side and said lower pressure side of said blade body, said new trailing edge is formed by an intersection between a first side of said trailing edge cap and a second side of said trailing edge cap, said first side is mounted on said higher pressure side, and said second side is mounted on said lower pressure side. 18. A blade in accordance with claim 15 wherein said trailing edge cap comprises a polyimide. 19. A blade in accordance with claim 15 wherein said trailing edge cap is mounted on said blade body adjacent a tip of said blade body. 20. A method comprising: providing a trailing edge cap for a blade, wherein the trailing edge cap includes a body that includes a body edge portion having a first thickness defined between a higher pressure side of the body edge portion and a lower pressure side of the body edge portion when the body is mounted on the blade; and mounting the trailing edge cap on the blade such that the trailing edge cap at least partially covers a trailing edge portion of the blade having a second thickness, the first thickness less than the second thickness. 21. A method in accordance with claim 20 wherein said mounting the trailing edge cap on the blade comprises: mounting a first side of the trailing edge cap on a higher pressure side of the blade; and mounting a second side of the trailing edge cap on a lower pressure side of the blade, such that the trailing edge cap at least partially covers a trailing edge portion of the blade formed by an intersection between the higher and lower pressure sides.
