What is claimed is: 1. A hinge apparatus comprising: a first hinge part having a first mounting plate and first and second side plates; a second hinge part having a second mounting plate and third and fourth side plates, said third and fourth side plate being disposed between said first and second side plates; and a hinge pin assembly extending between said first, second, third and fourth side plates and permitting relative pivotal movement of said first and second hinge parts about an axis of rotation defined by said hinge pin assembly; said hinge pin assembly comprising: a pin having a flat sided shank portion, a head and a threaded end, said head disposed adjacent one of said first and second side plates and said threaded end received in the other of said first and second side plates, said pin being fixed with respect to a longitudinal direction of the axis of rotation extending between the first and second side plates; a first cam plate on said pin and associated with one of said first hinge part and said second hinge part for rotation therewith, said first cam plate having a first contoured surface; a second cam plate having a flat sided axial opening disposed on said flat sided shank portion on said pin and associated with the other of said first hinge part and said second hinge part for rotation therewith, said second cam plate having a second contoured surface disposal against said first contoured surface; said first and second cam plates being disposed between said third and fourth side plates; and biasing means urging said first and second contoured surfaces into cooperative engagement; wherein said first and second contoured surfaces are configured and arranged to create a plurality of dwell points such that said first and second hinge parts can be held in a plurality of positions between open and closed positions. 2. The hinge apparatus of claim 1, said first and second cam plates disposed adjacent one of said third and fourth side plates, and said biasing means comprising a spring disposed between the other one of said third and fourth side plates and said cam plates. 3. A hinge apparatus providing at least one intermediate dwell position, said hinge apparatus comprising: a first hinge part and a second hinge part having interrelating structures; and a hinge pin assembly interconnecting said interrelating structures permitting relative pivotal movement of said first and second hinge parts about an axis of rotation defined by said hinge pin assembly; said hinge pin assembly comprising: a pin; a first cam plate on said pin and associated with one of said first hinge part and said second hinge part for rotation therewith, said first cam plate having a first contoured surface; a second cam plate on said pin and associated with the other of said first hinge part and said second hinge part for rotation therewith, said second cam plate having a second contoured surface disposed against said first contoured surface; biasing means urging said first and second contoured surfaces into cooperative engagement; a third cam plate on said pin and associated with one of said first and second hinge parts for rotation therewith, said third cam plate having a third contoured surface; a fourth cam plate on said pin and associated for rotation with the one of said first and second hinge parts not associated with said third cam plate, said fourth cam plate having a fourth contoured surface disposed against said third contoured surface; and said biasing means urging said third and fourth contoured surfaces into cooperative engagement. 4. The hinge apparatus of claim 3, said pin having a threaded end, and one of said interrelating structure defining a threaded enlargement for engaging said threaded end. 5. The hinge apparatus of claim 3, said first and second cam plates spaced from said third and fourth cam plates, and said biasing means disposed therebetween. 6. The hinge apparatus of claim 5, said biasing means comprising a spring. 7. The hinge apparatus of claim 5, said biasing means comprising belleville washers. 8. A vehicle hinge apparatus for controlling swinging movement of a vehicle door, while providing intermediate dwell points in said movement, said hinge apparatus comprising: a body hinge part including a first mounting plate and first and second side plates in spaced relation; a door hinge part including a second mounting plate and third and fourth side plates in spaced relation, said third and fourth side plates disposed between said first and second side plates; and a hinge pin assembly interconnecting said first, second, third and fourth side plates, said hinge pin assembly including: a hinge pin having a flat sided shank portion and a non-circular body portion located on one end thereof, said non-circular body portion being sized and shaped to be received by a mating portion in one of said body hinge part and said door hinge part; a first cam plate disposed on said pin, said first cam plate having a first contoured surface and being connected to one of said body hinge part and said door hinge part for rotation therewith; a second cam plate having a flat sided axial opening disposed on said flat sided shank portion of said pin, said second cam plate having a second contoured surface and being connected to the other of said body hinge part and said door hinge part for rotation therewith; said first and second cam plates disposed between said third and fourth side plates; a spring disposed on said pin between said third and fourth side plates urging said first and second contoured surfaces into operative engagement; and a cap secured to a end of said hinge pin that is opposite to said end of said pin having said non-circular body portion, said cap including a cylindrical body portion that is sized and shaped to be received rotatably by a mating portion in the other of said body hinge part and said door hinge part. 9. The vehicle hinge apparatus of claim 8, said pin having a threaded end, and one of said first and second side plate defining a threaded enlargement for engaging said threaded end. 10. A vehicle hinge apparatus for controlling swinging movement of a vehicle door, while providing intermediate dwell points in said movement, said hinge apparatus comprising: a body hinge part including a first mounting plate and first and second side plates in spaced relation; a door hinge part including a second mounting plate and third and fourth side plates in spaced relation; and a hinge pin assembly interconnecting said first, second, third and fourth side plates, said hinge pin assembly including: a hinge pin; a first cam plate disposed on said pin, said first cam plate having a first contoured surface and being connected to one of said body hinge part and said door hinge part for rotation therewith; a second cam plate disposed on said pin, said second cam plate having a second contoured surface and being connected to due other of said body hinge part and said door hinge part for rotation therewith; spring using said first and second contoured surfaces into operative engagement; third and fourth cam plate disposed on said pin, said third and fourth cam plates having third and fourth contoured surfaces, respectively, and said spring means urging said third and fourth contoured surfaces into cooperative engagement. 11. The vehicle hinge apparatus of claim 10; said third cam plate associated with one of said first and second cam plates for relative rotation therewith, and said fourth cam plate associated with the other of said first and second cam plates for relative rotation therewith; and said first and second cam plates being disposed on said pin spaced from said third and fourth cam plates disposed on said pin, and said spring means disposed therebetween. 12. The vehicle hinge apparatus of claim 11, said spring means comprising a coil spring. 13. The vehicle hinge apparatus of claim 11, said spring means comprising belleville washers.
