1. A handheld heating pump dispenser comprising a reusable housing, a printed circuit board having a heat generating portion, a heating chamber having an exit orifice, a reservoir that is able to hold a flowable product, a dispensing system, an actuator, a flexible conduit, and a product flow path from the reservoir to the exit orifice, wherein: the reusable housing is interiorly divided into a first section and a second section; a first potion of the printed circuit board is housed in the first section, and is able to form electrical contact with a power source;a second portion of the printed circuit board supports the heat generating portion inside the heating chamber;the reservoir is housed in the second section;a first portion of the dispensing system is disposed in the reservoir;a second portion of the dispensing system communicates with the actuator in a liquid tight fit;the product flow path comprises (in order) the reservoir, the dispensing system, the actuator, the flexible conduit, the heating chamber, and the heating chamber exit orifice; and whereinproduct is urged along the flow path as a result of depressing the actuator. 2. The dispenser of claim 1 further comprising an electrical switch that has at least two positions, in at least one of the positions the switch effects electrical contact between the heat generating portion and the power source, and in at least one of the positions the switch interrupts electrical contact between the heat generating portion and the power source, wherein the switch is accessible from the outside the dispenser, and can be engaged, either directly or indirectly, by a finger of a user. 3. The dispenser of claim 1 wherein the reusable housing has a removable cover that provides access to the second section of the reusable housing, the access allowing the reservoir and dispensing system to be removed from the reusable housing and a new reservoir and dispensing system to be put into the reusable housing. 4. The dispenser of claim 1 wherein the dispensing system is a metered dose mechanical pump that is able to dispense 50-500 μL of product in a single dose. 5. The dispenser of claim 4 wherein the actuator includes a product flow path comprising an actuator inlet, an actuator channel, and an actuator exit orifice, and wherein the dispenser further comprises: a stationary dispensing head that has a product flow path comprising a dispensing head inlet, the heating chamber, and the heating chamber exit orifice;and wherein the flexible conduit has a first end that is in fluid communication with the actuator exit orifice, and a second end that is in fluid communication with the dispensing head inlet. 6. The dispenser of claim 2 wherein the heat generating portion comprises a plurality of discrete, fixed value resistive heating elements. 7. The applicator of claim 6 wherein the printed circuit board comprises a substrate that is non-conductive to electricity, and that supports electronic components and electrical leads that are effective to connect the heat generating portion to the power source. 8. The dispenser of claim 7 further comprising an elongated printed circuit board housing that has the printed circuit board reposed through it, with portions of the printed circuit board emerging from both ends of the printed circuit board housing. 9. The dispenser of claim 7 that automatically turns off the heat generating portion about 30 seconds after the heat generating portion has reached a predetermined temperature. 10. The dispenser of claim 9 which includes a voltage divider circuit and a thermistor. 11. The dispenser of claim 10 which further comprises an operational amplifier and an N-channel MOSFET switch. 12. The dispenser of claim 6 wherein the heating elements are a bank of fixed value resistors electronically arranged in series, parallel, or any combination thereof, and physically situated in two rows, one on both sides of the printed circuit board. 13. The dispenser of claim 12 wherein the fixed value resistors have rated resistances from 1 to 10 ohms. 14. The dispenser of claim 13 wherein the overall resistance of all the heating elements ranges from 1 to 10 ohms. 15. The dispenser of claim 12 wherein the resistive heating elements are metal oxide thick film, chip resistors, the largest dimension of which is 2.0 mm or less. 16. The dispenser of claim 12 wherein the resistive heating elements are discrete dots of a metal oxide thick film, provided as a silk screen deposit on the printed circuit board. 17. The dispenser of claim 16 wherein the metal oxide thick film is comprised of ruthenium oxide (RuO2), and each dot is 2.0 mm or less. 18. The dispenser of claim 6 wherein the heat generating portion further comprises a protective tip that covers the resistive heating elements. 19. The dispenser of claim 18 wherein the resistive heating elements are embedded in a continuous, solid mass of a heat transfer material. 20. The dispenser of claim 19 wherein the heat transfer material is one or more thermally conductive adhesives, one or more thermally conductive encapsulating epoxies or a combination of these. 21. The dispenser of claim 2 further comprising a battery that has a terminal, and the terminal may alternately occupy at least one “on” position and at least one “off” position, according to the positioning of the switch. 22. The dispenser of claim 21 wherein the terminal directly contacts a conductive element on the printed circuit board, when the terminal is on the “on” position. 23. The dispenser of claim 21 wherein the battery is a 2.5 to 3.5 volt battery, having a capacity of 1,400 mAmp-hours or more. 24. The dispenser of claim 23 wherein the battery is based on lithium/manganese dioxide chemistry and having no mercury. 25. The dispenser of claim 21, wherein the battery is rechargeable. 26. The dispenser of claim 21, wherein the battery is replaceable through a door in the reusable housing. 27. The dispenser of claim 1 wherein a portion of the exterior surface of the dispenser is fashioned from a thermochromic material, such that the thermochromic material changes color within 10 seconds of the product in the chamber reaching a product application temperature. 28.
