1. An apparatus for dispensing one or more bulk products in response to inputs from a user for selecting one of the bulk products and a desired quantity, said apparatus comprising: a communication bus;one or more bin units, each of said bin units comprising a bin and an integrated dispensing mechanism, and further including a dedicated control unit, said bin comprising a sealable housing and being configured to hold one of the bulk products, said control unit including an addressable communication interface coupled to said communication bus, and said control unit being operatively coupled to said dispensing mechanism and configured to control said dispensing mechanism in response to one or more control commands addressed to said control unit and received over said communication bus;a controller configured to receive the inputs from the user and generate one or more control commands for dispensing the selected bulk product in the desired quantity, and said controller including a control/command interface for addressing said bin unit associated with the selected bulk product and transmitting said one or more generated control commands to said bin unit over said communication bus;said communication bus comprising a modular configuration for coupling a plurality of said bin units; andeach of said dispensing mechanisms comprising a motor and a dispensing device, said dispensing device being operatively coupled to said motor and actuated by said motor, and said motor being operatively connected to said control unit and configured to be responsive to one or more control signals from said control unit to actuate said dispensing device, and said one or more control signals being generated based on said one or more control commands addressed to said control unit;said dispensing mechanism comprising a chute for dispensing the desired quantity of the selected bulk product contained in said bin into a container. 2. The apparatus as claimed in claim 1, wherein said control commands comprise an identification field configured to store an address for the associated bin unit or an address for the controller. 3. The apparatus as claimed in claim 2, wherein said control commands comprise an inquiry command, a vending process start command, a vending process stop command, and a vending process error stop command. 4. The apparatus as claimed in claim 3, wherein said control unit is configured to respond to said inquiry command, and said response comprises storing said address for said controller in said identification field and transmitting said inquiry command over said communication bus to said controller. 5. The apparatus as claimed in claim 3, wherein said vending process start command includes a bin identification field and said bin identification field is configured to store a value corresponding to said bin unit containing the bulk product selected by the user. 6. The apparatus as claimed in claim 3, wherein said control unit is configured to generate said vending process error stop command when an error condition occurs, and the identification field of said vending process error stop command stores the address for the controller and is transmitted over said communication bus. 7. The apparatus for dispensing as claimed in claim 1, wherein said dispensing mechanism further includes a load cell, said load cell being operatively coupled to said control unit and configured to measure the quantity of selected bulk product being dispensed. 8. The apparatus for dispensing as claimed in claim 1, wherein said dispensing mechanism further includes an agitation mechanism responsive to said control unit and configured to agitate the bulk product in the bin so as to keep the bulk product from sticking. 9. A method for dispensing bulk products from one or more bins, each of the bins including a dispensing mechanism and a control unit operatively coupled to the dispensing mechanism and the control unit further including a control command communication interface for receiving control commands addressed to the bin, said method comprising the steps of: receiving a bulk product selection from a user;receiving a bulk product dispensing amount from the user;generating a vending process control command comprising an identification field storing an address corresponding to the bin holding the selected bulk product and a bulk product amount field storing a value corresponding to the selected bulk product dispensing amount;transmitting said vending process control command over a communication network;receiving said vending process control command at the communication interface;inputting said vending process control command if said identification field matches the address of the bin;activating a motor drive integrated with the bin;monitoring a load cell for measuring the selected bulk product being dispensed and controlling said integrated motor drive to dispense the selected bulk product from the bin in the amount specified in said bulk product amount field. 10. The method as claimed in claim 9, further including the step of generating a vending process error command and transmitting said vending process error command to a central controller in response to an error condition. 11. The method as claimed in claim 10, further including the step of suspending operation of the bin unit originating said vending process error command. 12. The method as claimed in claim 9, wherein the value stored in said bulk product amount field corresponds to a dollar value specified by the user. 13. The method as claimed in claim 9, wherein the value stored in said bulk product amount field corresponds to a bulk product quantity specified by the user. 14. The method as claimed in claim 9, further including the step of agitating at least a portion of the selected bulk product to prevent sticking or clumping of the selected bulk product during dispensing. 15. A modular bin unit for use with an apparatus for vending a bulk product, said modular bin unit comprising: a bin comprising a sealable enclosure and being configured to hold a quantity of the bulk product;an integrated dispensing mechanism and said integrated dispensing mechanism comprising a motor and a dispensing device, said dispensing device being operatively coupled to said motor and actuated by said motor, and said motor being operatively connected to said control unit and configured to be responsive to one or more control signals from said control unit to actuate said dispensing device;a control unit including an addressable communication interface for coupling to a communication bus; andsaid control unit being operatively coupled to said dispensing mechanism and configured to generate said one or more control signals for controlling said dispensing mechanism in response to one or more control commands addressed to said control unit and received over said communication bus. 16. The modular bin as claimed in claim 15, wherein said control commands comprise an identification field configured to store an address for identifying the associated modular bin unit. 17. The modular bin as claimed in claim 16, wherein said control commands comprise an inquiry command, a vending process start command, a vending process stop command, and a vending process error stop command. 18. The modular bin as claimed in claim 17, wherein said control unit is configured to respond to said inquiry command, and said response comprises storing an address for a central controller in said identification field and transmitting said inquiry command over said communication bus to said central controller. 19. The modular bin as claimed in claim 17, wherein said vending process start command includes a bin identification field and said bin identification field is configured to store a value corresponding to the modular bin unit containing the bulk product selected by the user. 20. The modular bin as claimed in claim 17, wherein said control unit is configured to generate said vending process error stop command when an error condition occurs, and the identification field of said vending process error stop command stores an address for the central controller and is transmitted over said communication bus. 21. The modular bin unit as claimed in claim 15, wherein said dispensing mechanism further includes a load cell, said load cell being operatively coupled to said control unit and configured to measure the quantity of selected bulk product being dispensed. 22. The modular bin unit as claimed in claim 15, wherein said dispensing mechanism further includes an agitation mechanism responsive to said control unit and configured to agitate the bulk product in the bin so as to keep the bulk product from sticking.
