1. A rotational limit stop comprising:a substantially circular disc having an upper surface, a lower surface and a perimeter surface, the perimeter surface containing a plurality of teeth on one portion thereof,a central aperture passing through the center of the circular disc, anda plurality of resilient spring legs extending downwards from the lower surface of the disc, such that the resilient spring legs of the rotational limit stop flex to accommodate the compression forces as a faucet assembly containing the rotational limit stop is being assembled. 2. The rotational limit stop according to claim 1, wherein the perimeter surface of the disc is divided into a teeth section containing the plurality of teeth, an indented section, and a smooth section. 3. The rotational limit stop according to claim 2, further comprising:a handle tab extending above and below the disc adjacent to the perimeter surface, the handle tab being situated in the smooth portion of the disc; anda stop wall also extending upwards from the upper surface of the disc adjacent the perimeter surface, the stop wall also being situated in the smooth portion of the disc but spaced apart from the handle tab. 4. The rotational limit stop according to claim 3, wherein the disc contains an annular portion immediately surrounding the central aperture, the annular portion being raised above the upper surface of the disc. 5. The rotational limit stop according to claim 4, further comprising:a plurality of temperature indicating bumps raised above the upper surface of the disc and situated in the indented portion of the disc; anda calibration line situated with, but distinguished from, the temperature indicating bumps. 6. The rotational limit stop according to claim 5, wherein the temperature indicating bumps are spaced apart such that each bump corresponds to approximately three degrees Fahrenheit when the rotational limit stop is installed within a faucet assembly. 7. The rotational limit stop according to claim 6, wherein the rotational limit stop is constructed as a single unit from an elastomeric material. 8. A faucet assembly comprising:a valve assembly having a valve sprocket extending axially therefrom, the valve sprocket having teeth around its perimeter;a flow control knob fitted onto the valve assembly, the flow control knob having 1) a central opening, the central opening having mating ridges around its perimeter, 2) a base surface extending radially from the central opening, 3) a perimeter lip surrounding the base surface, the perimeter lip having an inner surface, and 4) a plurality of engaging ridges along the inner surface of the perimeter lip, such that the valve sprocket extends through the central opening of the flow control knob;a rotational limit stop fitted within the flow control knob, the rotation limit stop comprising 1) a substantially circular disc having an upper surface, a lower surface and a perimeter surface, the perimeter surface containing a plurality of teeth, 2) a central aperture passing through the center of the circular disc, 3) a plurality of resilient spring legs extending downwards from the lower surface of the disc, such that the teeth around the perimeter surface engage the engaging ridges along the inner surface of the perimeter lip, thereby causing the rotational limit stop to rotate with the flow control knob;a temperature knob fitted onto of the rotational limit stop; anda temperature knob cover, covering the temperature knob, wherein the resilient spring legs of the rotational limit stop flex to accommodate the compression forces as the faucet assembly is being assembled. 9. The faucet assembly according to claim 8, wherein the disc of the rotational limit stop contains an annular portion immediately surrounding the central aperture, the annular portion being raised above the upper surface of the disc. 10. The faucet assembly according to claim 9, wherein the downwardly extending spring legs are situated outside of the raised annular portion of the disc. 11. The faucet assembly according to claim 10, further comprising:a plurality of temperature indicating bumps raised above the upper surface of the disc of the rotational limit stop, and situated in the indented portion of the disc; anda calibration line situated with, but distinguished from, the temperature indicating bumps. 12. The faucet assembly according to claim 11, wherein the rotational limit stop is constructed as a single unit from an elastomeric material.
