What is claimed is: 1. A combination chair and leg extension apparatus, comprising: a chair having a generally L-shaped frame on which is disposed a seat portion and a back portion, and a base portion having legs extending below the frame to the floor, the seat portion having a top surface for sitting and a bottom surface opposed to the top surface, a tilt up means disposed between the frame and the base portion to permit selective pivoting of the frame into a position in which a front edge of the frame is spaced away from the base, a leg extension apparatus attached to the chair, the apparatus comprising: a telescoping tube member mounted in a longitudinal orientation on the bottom surface of the seat portion, the tube having at least two segments concentrically arranged for telescopic movement in relation to each other, the tube having a front end disposed toward the front of the chair and a back end disposed toward the back of the chair, a flexor leg pivotally mounted to the front end of the tube and terminating in a pair of foot stirrups, and a pneumatic resistor connecting the flexor leg to the back end of the tube, the apparatus permitting a user seated in the chair to engage the stirrups with the user's feet and, using the force of the user's leg strength to overcome the resistence provided by the resistor, to kick the flexor leg from a position below the seat portion forward in an arc, thereby drawing forward the tube to fully extend the flexor leg and the tube forwardly away from the chair, wherein the tilt up means, when tilted up, provides clearance for the flexor leg and the user's feet to sweep below the seat portion without touching the floor, and when not tilted, allows the chair to be used in the manner of a standard chair wherein the user's feet touch the floor. 2. The combination chair and leg extension apparatus of claim 1, wherein the arc described by the stirrup end of the flexor leg does not touch the floor at any point. 3. The combination chair and leg extension apparatus of claim 1, wherein the arc described by the stirrup end of the flexor leg does not touch any portion of the chair. 4. The combination chair and leg extension apparatus of claim 1, wherein the tilt up means provides clearance between the flexor leg and the floor. 5. The combination chair and leg extension apparatus of claim 1, wherein the apparatus has a stowed position wherein the flexor leg is positioned under the frame of the chair and the tube is in a retracted state, and wherein the apparatus in the stowed position does not extend in any direction beyond the outer dimensions of the chair. 6. The combination chair and leg extension apparatus of claim 1, wherein the apparatus has a stowed position wherein the flexor leg is positioned under the frame of the chair and the tube is in a retracted state, and wherein the apparatus in the stowed position does not extend in any direction outside an area bounded by the legs of the chair. 7. The combination chair and leg extension apparatus of claim 1, wherein the flexor leg comprises a generally S-shaped member. 8. A combination desk, chair and leg extension apparatus, comprising: a combination desk and chair having a generally U-shaped frame on which is disposed at one end a desk platform, and at the other end a chair, the chair having a generally L-shaped frame on which is disposed a seat portion and a back portion, and a base portion connected to the U-shaped frame, the seat portion having a top surface for sitting and a bottom surface opposed to the top surface, a leg extension apparatus attached to the chair, the apparatus comprising: a telescoping tube member mounted in a longitudinal orientation on the bottom surface of the seat portion, the tube having at least two segments concentrically arranged for telescopic movement in relation to each other, the tube having a front end disposed toward the front of the chair and a back end disposed toward the back of the chair, a flexor leg pivotally mounted to the front end of the tube and terminating in a pair of foot stirrups, a pneumatic resistor connecting the flexor leg to the back end of the tube, the apparatus permitting a user seated in the chair to engage the stirrups with the user's feet and, using the force of the user's leg strength to overcome the resistence provided by the resistor, to kick the flexor leg forward in an arc, thereby drawing forward the tube to fully extend the flexor leg and tube forwardly away from the chair. 9. The combination desk, chair and leg extension apparatus of claim 8, wherein the desk platform is adjustable to raise or lower the height. 10. The combination desk, chair and leg extension apparatus of claim 8, wherein the U-shaped frame is adjustable to vary the space between the chair and the desk to provide clearance for the extension of the leg extension apparatus when in use. 11. A combination office chair and leg extension apparatus, comprising: an office chair having a generally L-shaped frame on which is disposed a seat portion a back portion and two arm rests, and a pedestal base portion extending below the frame to the floor, the pedestal base portion being height adjustable to selectively vary the distance between the frame and the floor, a leg extension apparatus having two leg extension assemblies, each assembly attached to an arm rest of the chair and comprising: a flexor leg pivotally mounted to the arm rest; a telescoping tube member connected to and extending beyond the flexor leg, the tube having at least two segments concentrically arranged for telescopic movement in relation to each other, and terminating in a pair of foot stirrups, and a pneumatic resistor connecting the flexor leg to a back end of the arm rest, the apparatus permitting a user seated in the chair to pivot forward the apparatus from the stowed position and to engage the stirrups with the user's feet and, using the force of the user's leg strength to overcome the resistence provided by the resistor, to kick the flexor leg forward in an arc, thereby drawing forward the tube to fully extend the flexor leg and tube forwardly away from the chair, wherein the pedestal base portion can be raised to provide clearance for the flexor legs and the user's feet to sweep below the seat portion without touching the floor, and can be lowered to allow the chair to be used in the manner of a standard chair wherein the user's feet touch the floor. 12. The combination office chair and leg extension apparatus of claim 11, wherein the office chair further comprises a tilt up means disposed between the frame and the base portion to permit selective pivoting of the frame into a position in which a front edge of the frame is spaced away from the base. 13. The combination office chair and leg extension apparatus of claim 11, wherein the height adjustable pedestal base permits clearance between the arc described by the apparatus and the floor. 14. The combination office chair and leg extension apparatus of claim 11, wherein the apparatus does not touch the floor at any point. 15. The combination office chair and leg extension apparatus of claim 11, wherein the apparatus does not touch the pedestal base at any point. 16. The combination chair and leg extension apparatus of claim 1, further comprising a desk. 17. The combination office chair and leg extension apparatus of claim 11, further comprising a desk.
