1. An apparatus comprising: an airfoil;a flexible skin forming a control surface of the airfoil; anda shape control system capable of changing a shape of the control surface formed by the flexible skin between a plurality of shapes, wherein the shape control system comprises a plurality of rollers capable of engaging an interior surface of the of the flexible skin, wherein the plurality of rollers comprises a first plurality of leading edge rollers arranged in a first array and a second plurality of drag rollers arranged in a second array that is substantially parallel to the first array. 2. The apparatus of claim 1, wherein the shape control system further comprises: a linkage system connected to the plurality of rollers and capable of moving the plurality of rollers. 3. The apparatus of claim 2, wherein the shape control system further comprises: an actuator system capable of moving the linkage system. 4. The apparatus of claim 3, wherein the shape control system further comprises: an upper support plate capable of providing support to an upper part of the flexible skin in an undeployed shape in the plurality of shapes. 5. The apparatus of claim 1 further comprising: a rigid skin forming another portion of the airfoil. 6. The apparatus of claim 5, wherein the flexible skin is adjacent to the rigid skin and forms a contiguous skin surface. 7. The apparatus of claim 1, wherein the flexible skin is located at an edge of the airfoil and wherein changing from an undeployed shape to a deployed shape causes the edge of the airfoil to increase a bluntness of the edge and a droop angle of the edge. 8. The apparatus of claim 1, wherein the control surface is selected from one of a leading edge of the airfoil, a trailing edge of the airfoil, a spoiler, a flap, an elevator, a rudder, a slat, and an airbrake. 9. The apparatus of claim 1, wherein the airfoil is an aircraft wing. 10. The apparatus of claim 1 further comprising: an object, wherein the airfoil is connected to the object, wherein the object is selected from one of a mobile platform, an aircraft, a surface ship, a tank, a personnel carrier, a train, a spacecraft, a submarine, a bus, and an automobile. 11. The apparatus of claim 1, wherein the flexible skin is an elastic skin. 12. An aircraft comprising: an airfoil;a flexible skin forming a portion of a surface of the airfoil;a first rigid skin forming another portion of the surface of the airfoil;a second rigid skin forming yet another portion of the surface of the airfoil, wherein the flexible skin extends between the first rigid skin and the second rigid skin and is adjacent to the first rigid skin and the second rigid skin to form a contiguous skin surface for the airfoil;a roller system capable of engaging an interior surface of the flexible skin, wherein the roller system comprises leading edge rollers and drag rollers having a different diameter from the leading edge rollers;a plurality of linkages coupled to the roller system; andan actuator system capable of moving the plurality of linkages in a manner that causes the roller system to move against an interior of the flexible skin to change a shape of a portion of the flexible skin between the first rigid skin and the second rigid skin,wherein the flexible skin remains adjacent to the first rigid skin and the second rigid skin when the actuator system is moving the plurality of linkages to change the shape of the flexible skin. 13. The aircraft of claim 12, wherein the flexible skin is located at a leading edge of the airfoil, and wherein the leading edge rollers are capable of being moved by the plurality of linkages into a position that increases a bluntness of the leading edge, and wherein the drag rollers are capable of being moved to a deployed shape to increase a droop angle of the leading edge. 14. The aircraft of claim 12 further comprising: an upper support plate capable of providing support to an upper part of the flexible skin in an undeployed shape in the plurality of shapes. 15. The aircraft of claim 12, wherein the flexible skin is an elastic skin.
