What is claimed is: 1. A dual annular combustor for a gas turbine engine, said combustor comprising a spectacle plate comprising an inner annulus and an outer annulus, and a plurality of pairs of swirlers attached to said spectacle plate, each of said pair of swirlers comprises an inner swirler coupled to said inner annulus and an outer swirler coupled to said outer annulus, each said swirler comprising a pair of substantially parallel flats, wherein to assemble said combustor: an assembly fixture is coupled to one pair of said swirlers, wherein said assembly fixture includes a plurality of arms that are sized to receive and align said flats of each said swirler with respect to each other and an attachment portion that is configured to couple to said spectacle plate; said assembly fixture is removably coupled to said spectacle plate to facilitate maintaining an alignment of each said swirler with respect to said spectacle plate; each remaining swirler is then coupled to said spectacle plate; and said assembly fixture is then uncoupled from said spectacle plate after each said swirler is attached to said spectacle plate. 2. A combustor in accordance with claim 1 further comprising a plurality of deflector plates comprising an opening extending therethrough, wherein to assemble said combustor, said plurality of deflector plates are each attached to said spectacle plate such that wherein each said deflector plate opening is substantially concentrically aligned with each respective said swirler. 3. A combustor in accordance with claim 2 wherein each said swirler is welded to said spectacle plate prior to uncoupling each respective assembly fixture. 4. A combustor in accordance with claim 2 wherein to assemble said combustor further comprises: a first of said deflector plates is positioned against said spectacle plate; a second of said deflector plates is positioned against said spectacle plate and circumferentially adjacent said first deflector plate; and an alignment fixture is removably coupled between said first and second deflector plates to maintain a position of said first and second deflector plates with respect to said spectacle plate. 5. A combustor in accordance with claim 4 wherein each said deflector plate is brazed to said spectacle plate, and wherein each respective alignment fixture is removed after said first and second deflector plates are secured to said spectacle plate during assembly of said combustor.
