1. A fluid transfer assembly for use in a gas turbine engine, said fluid transfer assembly comprising: a rotor shaft;a stationary assembly circumscribing said rotor shaft; anda rotating component coupled to said rotor shaft and positioned radially inward of said stationary assembly, said rotating assembly comprising: a hub coupled to said rotor shaft;a plurality of rotor blades coupled to said hub; anda shroud coupled to said plurality of rotor blades, wherein the hub, the plurality of rotor blades, and the shroud are together integrally formed as a unitary, monolithic component. 2. The assembly in accordance with claim 1, wherein said shroud extends circumferentially relative to said plurality of rotor blades to form a disk shape. 3. The assembly in accordance with claim 1, wherein said shroud comprises arcuate shape that is complementary to an outer profile of said plurality of rotor blades. 4. The assembly in accordance with claim 1, wherein each rotor blade of said plurality of rotor blades comprises a leading edge and an opposing trailing edge that defines a rotor blade length therebetween, wherein said shroud extends substantially a full distance of the rotor blade length. 5. The assembly in accordance with claim 1, wherein each rotor blade of said plurality of rotor blades comprises a leading edge and an opposing trailing edge that defines a rotor blade length therebetween, wherein said shroud extends from at least one of said leading edge and said trailing edge to a shroud end a distance less than the length of said rotor blade. 6. The assembly in accordance with claim 5, wherein said stationary assembly comprises a sealing member positioned adjacent said plurality of rotor blades, wherein said sealing member extends away from said shroud between said shroud end and one of said leading edge or said trailing edge. 7. The assembly in accordance with claim 1, wherein said stationary assembly comprises at least one sealing element positioned proximate at least one of said leading edge and said trailing edge. 8. The assembly in accordance with claim 7, wherein said rotating component comprises at least one tooth coupled to said shroud, said at least one tooth configured to form a seal with said at least one sealing element. 9. The assembly in accordance with claim 1, wherein said rotating component comprises at least one of a centrifugal compressor and a centrifugal turbine. 10. A centrifugal compressor for use in a gas turbine engine including a rotor shaft, said centrifugal compressor comprising: a hub coupled to the rotor shaft;a plurality of rotor blades coupled to said hub, said plurality of rotor blades comprising an outer edge; anda shroud coupled to said outer edge of said plurality of rotor blades such that a flowpath is formed between said shroud and said hub, wherein the hub, the plurality of rotor blades, and the shroud are together integrally formed as a unitary, monolithic component. 11. The centrifugal compressor in accordance with claim 10, wherein said shroud extends circumferentially relative to said plurality of rotor blades to form a disk shape. 12. The centrifugal compressor in accordance with claim 10, said shroud comprises arcuate shape that is complementary to an outer profile of said plurality of rotor blades. 13. The centrifugal compressor in accordance with claim 10, wherein each rotor blade of said plurality of rotor blades comprises a leading edge and an opposing trailing edge that defines a rotor blade length therebetween, wherein said shroud extends substantially a full distance of the rotor blade length. 14. The centrifugal compressor in accordance with claim 10, wherein each rotor blade of said plurality of rotor blades comprises a leading edge and an opposing trailing edge that defines a rotor blade length therebetween, wherein said shroud extends from at least one of said leading edge and said trailing edge to a shroud end a distance less than the length of said rotor blade. 15. The centrifugal compressor in accordance with claim 10 further comprising at least one seal tooth coupled to said shroud, said at least one tooth configured to form a seal with a stationary assembly positioned proximate said shroud in the gas turbine engine. 16. A method of manufacturing a centrifugal compressor for use in a gas turbine engine, said method comprising: integrally forming a plurality of blades with a hub, the hub configured to be coupled to a rotor shaft; andintegrally forming a shroud with an outer edge of the plurality of rotor blades to form a flowpath defined between the shroud and the hub, wherein the hub, the plurality of rotor blades, and the shroud are together integrally formed as a unitary, monolithic component. 17. The method in accordance with claim 16, wherein integrally forming the shroud comprises integrally forming the shroud such that the shroud extends substantially a full distance of the plurality of rotor blades. 18. The method in accordance with claim 16, wherein integrally forming the shroud comprises integrally forming the shroud such that the shroud extends a distance along the plurality of rotor blades less than a full length of the rotor blades.
