1. A combustor component comprising: a distributor body having an axis and an annular outer surface;one or more fuel conduits located within the distributor body, the one or more fuel conduits oriented in a substantially axial direction;a main fuel circuit located within the distributor body, the main fuel circuit oriented in a circumferential direction around the axis and communicating with each of the one or more fuel conduits at a corresponding fuel inlet;a circumferential row of fuel orifices located in the distributor body in flow communication with the main fuel circuit, each orifice extending in a substantially radial direction and communicating with the outer surface, wherein a cross section area of the main fuel circuit varies in the circumferential direction;wherein the distributor body and fuel conduits are monolithically formed as a single piece. 2. A combustor component according to claim 1 further comprising: an annular heat shield located at an axially aft end of the distributor body such that the heat shield is capable of shielding the distributor body from a flame located axially aft from the distributor body. 3. A combustor component according to claim 2 wherein the distributor body has a circumferential row of axial openings capable of flowing cooling air towards the heat shield. 4. A fuel nozzle comprising: the combustor component of claim 1, andan annular air swirler located radially inside the distributor body and capable of swirling an air stream entering the annular air swirler; anda fuel injector located radially inside the annular air swirler capable of injecting a stream of fuel into a mixing chamber such that the fuel and air are mixed within the mixing chamber. 5. A fuel nozzle according to claim 4 further comprising: an annular fuel distributor comprising a single monolithic element, the single monolithic element further comprising a center body having an annular outer wall surrounding the distributor body and having at least one circumferential row of openings corresponding to a plurality of fuel orifices located within the distributor body arranged circumferentially around the axis. 6. A fuel nozzle according to claim 5 further comprising: the at least one circumferential row of openings located on the outer wall capable of flowing cooling air over a portion of the outer wall. 7. A fuel nozzle according to claim 6 wherein the at least one circumferential row of openings are diffuser holes. 8. A fuel nozzle according to claim 4 further comprising: an annular heat shield located at an aft end of a center body such that the annular heat shield is capable of shielding the center body from a flame located axially aft from the center body. 9. A fuel nozzle according to claim 8 further comprising: at least one row of axial flow holes located on the center body capable of flowing cooling air towards the annular heat shield. 10. The combustor component of claim 1 further comprising: a circumferential row of fuel posts extending radially outward from the outer surface of the distributor body;a center body having an annular outer wall surrounding the distributor body, the annular outer wall of the center body spaced apart from the outer surface of the distributor body in a radial direction so as to define an annular passage for air flow between the outer wall and the distributor body, and having a circumferential row of openings, each opening aligned with one of the fuel posts;wherein each orifice extends in a substantially radial direction through one of the fuel posts; andwherein the distributor body, fuel conduits, and the center body are monolithically formed as a single piece. 11. The combustor component of claim 1 wherein the main fuel circuit includes two or more separate fuel paths, each fuel path extending in a circumferential direction within the distributor body and communicating with one of the fuel inlets and a plurality of the fuel orifices.
