The apparatus according to claim 1 wherein the first engagement member is attached to the supply vessel and the second engagement member is attached to the applicator device.3. The apparatus according to claim 1, further comprising a collar that couples the first engagement member and the second engagement member.4. The apparatus according to claim 3, wherein the collar is configured to retain the protruding portion of the first engagement member and the concavity of the second engagement member.5. The apparatus according to claim 1 wherein the protruding portion comprises a partially spherical portion and wherein the concavity comprises a partially spherical concavity.6. The apparatus according to claim 1 wherein the protruding portion is rotatably and pivotally moveable within the concavity.7. The apparatus according to claim 1 wherein the first engagement member includes a recessed portion proximate the protruding portion, the recessed portion being sized to receive a portion of the second engagement member when the second engagement member is pivoted with respect to the first engagement member.8. The apparatus according to claim 1 wherein the second engagement member includes an outer wall surrounding the concavity, the outer wall including a tapered end portion.9. The apparatus according to claim 1 wherein the second engagement member includes an outer wall surrounding the concavity, the outer wall including a tapered end portion, and wherein the first engagement member includes recessed portion proximate the protruding portion, the recessed portion being sized to at least partially receive the tapered end portion when the second engagement member is pivoted with respect to the first engagement member.10. The apparatus according to claim 1 wherein the first engagement member is threadedly coupled to the supply vessel and the second engagement member is threadedly coupled to the applicator device.11. The apparatus according to claim 1, further comprising a pressure source coupled to the applicator device.12. A swivel assembly for coupling a gravity feed supply vessel to a spray gun applicator device having a dispenser assembly and a nozzle for applying a liquid coating material, comprising a first engagement member having a protruding portion and a first passageway disposed therethrough, and a second engagement member having a concavity and a second passageway disposed therethrough, the first passageway of the first engagement member and the second passageway of the concavity each having interior walls defining a fluid conduit, and, the protruding portion being moveably engaged within the concavity, the first passageway being in fluid communication with the second passageway such that the supply vessel fluidly communicates with the applicator device through the first and second passageways, whereby fluid flows through the fluid conduit in direct contact with the interior walls and whereby the gravity feed supply vessel is rotatable in any direction with respect to the spray gun applicator while maintaining the nozzle and the dispenser in a fixed orientation with respect to one another.13. The apparatus according to claim 12 wherein the protruding portion is rotatably and pivotally moveable within the concavity.14. The assembly according to claim 12, further comprising a collar that couples the first engagement member and the second engagement member.15. The apparatus according to claim 14, wherein the collar is configured to retain the protruding portion of the first engagement member within the concavity of the second engagement member.16. The apparatus according to claim 15, wherein the collar includes a first threaded portion and the second engagement member includes a second threaded portion engageable with the first threaded portion, the collar being selectively adjustable to obtain a desired positional orientation between the first engagement member and the second engagement member.17. The apparatus according to claim 12 wherein the protruding portion comprises a partially spherical protruding portion and wherein the concavity comprises a partially spherical concavity.18. The apparatus according to claim 12 wherein the first engagement member is adapted to be engaged with the supply vessel and the second engagement member is adapted to be engaged with the applicator device.19. A method of supplying a liquid material to a spray gun applicator device having a dispenser assembly and a nozzle, comprising:coupling a gravity feed supply vessel to the applicator device using a swivel assembly, the swivel assembly including a first engagement member having a concavity therein and a first passageway therethrough, and a second engagement member having a protrusion and a second passageway disposed therethrough, the protrusion being moveably engaged within the concavity and the first passageway being in fluid communication with the second passageway; the first passageway of the first engagement member and the second passageway of the concavity each having interior walls defining a fluid conduit, and providing the liquid material into the supply vessel; and flowing the liquid material from the supply vessel through the first and second passageways to the applicator device passageways whereby fluid flows through the fluid conduit in direct contact with the interior walls and whereby the gravity feed supply vessel is rotatable in any direction with respect to the spray un applicator while maintaining the nozzle and the dispenser in a fixed orientation with respect to one another. 20. The method according to claim 19 wherein coupling a supply vessel to the applicator device using a swivel assembly comprises coupling a supply vessel to the applicator device using a swivel assembly wherein the concavity comprises a partially spherical concavity and wherein the protrusion comprises a partially spherical protrusion.21. The method according to claim 19, wherein coupling a supply vessel to the applicator device using a swivel assembly further comprises coupling the first engagement member and the second engagement member with a collar.22. The method according to claim 21, wherein coupling the first engagement member and the second engagement member with a collar further comprises retaining at least a part of the protruding portion of the first engagement member within the concavity of the second engagement member.23. The method according to claim 22, wherein the collar includes a first threaded portion and the second engagement member includes a second threaded portion engageable with the first threaded portion, and retaining at least a part of the protruding portion of the first engagement member within the concavity of the second engagement member further comprises engaging the first threaded portion and the second threaded portion and applying a desired torque to the collar to retain a desired positional orientation between the first engagement member and the second engagement member.24.
