1. An electronic faucet comprising: a spout having a passageway configured to conduct fluid flow through the spout;an electrically operable valve coupled to the passageway; anda single capacitive sensor coupled to a portion of the faucet, the single capacitive sensor providing both a touch sensor and a proximity sensor for the electronic faucet. 2. The faucet of claim 1, wherein the capacitive sensor includes an electrode coupled to the spout. 3. The faucet of claim 1, further comprising a controller coupled to the capacitive sensor, the controller being configured to monitor an output signal from the capacitive sensor to detect when a portion of the faucet is touched by a user and to detect when a user's hands are located in a detection area located near the spout. 4. The faucet of claim 3, wherein the controller is configured to operate the faucet in one of a first mode of operation in which the proximity sensor is inactive and a second mode of operation in which the proximity sensor is active. 5. The faucet of claim 4, wherein the controller toggles the faucet between the first mode of operation and the second mode of operation in response to a predetermined pattern of touching of the faucet. 6. A method of controlling fluid flow in an electronic faucet having a spout, a passageway configured to conduct fluid flow through the spout, an electrically operable valve coupled to the passageway, a manual valve located in series with the electrically operable valve, and a manual handle configured to control the manual valve, the method comprising: providing a single capacitive sensor coupled to a portion of the faucet;monitoring an output signal from the capacitive sensor to detect when a user touches at least one of the spout and the manual valve handle and to detect when a user's hands are located in a detection area located near the faucet; andcontrolling the electrically operable valve is response to the step of monitoring the output signal. 7. The method of claim 6, further comprising: providing a first mode of operation of the faucet in which the proximity sensor is inactive;providing a second mode of operation of the faucet in which the proximity sensor is active; andselectively changing between the first and second modes of operation. 8. The method of claim 7, wherein the step of selectively changing between the first and second modes of operation comprises toggling the faucet between the first mode of operation and the second mode of operation in response to detecting a predetermined pattern of touching at least one of the spout and the manual valve handle. 9. The method of claim 6, wherein the monitoring step includes distinguishing between a user tapping one of the spout and the manual valve handle, a user grabbing the spout, and a user grabbing the manual valve handle. 10. The method of claim 6, further comprising toggling the electronic valve between open and closed positions in response to detecting a user touching one of the spout and the manual valve handle during the monitoring step. 11. The method of claim 6, wherein the capacitive sensor includes an electrode coupled to one of the spout and the manual valve handle. 12. The method of claim 11, wherein the electrode is coupled to the spout, and wherein the manual valve handle is at least partially formed from a conductive material, and further comprising an insulator located between the spout and the manual valve handle to capacitively couple the conductive manual valve handle to the electrode. 13. The method of claim 11, wherein the electrode is coupled to one of the spout and the manual valve handle by a single wire. 14. The method of claim 7, further comprising toggling the electrically operable valve from a closed position to an open position in response to detecting a user's hands in the detection area when the faucet is in the second mode of operation. 15. The method of claim 14, further comprising toggling the electrically operable valve from the open position to the closed position in response to detecting that the user's hands have been removed from the detection area. 16. The method of claim 15, further comprising delaying toggling the electrically operable valve from the open position to the closed position for a predetermined time after detecting that the user's hands have been removed from the detection area, and maintaining the valve in the open position if the user's hands are subsequently detected in the detection area within the predetermined time. 17. The method of claim 6, wherein the monitoring step includes distinguishing between a user tapping the spout and a user grabbing the spout, and wherein the controlling step includes starting fluid flow through the spout in response to detecting a user's hands in the detection area via a hands-free mode of operation, maintaining fluid flow via a touch mode if a tap of the spout is detected within a time period less than a predetermined time after the hands-free mode is initiated, and shutting off fluid flow through the spout if a tap of the spout is detected at a time greater than the predetermined time after initiation of the hands-free mode. 18. The method of claim 17, wherein the controlling step further comprises maintaining fluid flow through the spout via the touch mode if a grab of the spout is detected within a time period less than the predetermined time after initiation of the hands-free mode, and maintaining fluid flow via the hands-free mode if a grab of the spout is detected at a time greater than the predetermined time after initiation of the hands-free mode. 19. The method of claim 6, wherein the monitoring step includes distinguishing between the user tapping a spout and a user grabbing a spout, and wherein the controlling step includes starting fluid flow through the spout in a touch mode of operation in response to detecting either of a tap or a grab of the spout, maintaining fluid flow through the spout in the touch mode in response to detecting the user's hands in the detection area or in response to a grab of the spout, and shutting off fluid flow through the spout in response to detecting a subsequent tap of the spout. 20. The method of claim 6, wherein the controlling step includes starting fluid flow through the spout in response to detecting a user's hands in the detection area via a hands-free mode of operation and starting fluid flow through the spout in a touch mode of operation in response to detecting either of a tap or a grab of the spout, and wherein the method further includes actuating an indicator in first and second distinguishable patterns to provide an indication whether the faucet is operating in the hands-free mode of operation or the touch mode of operation.
