CROSS REFERENCES TO RELATED APPLICATIONS [0001] This application is a continuation of U.S. patent application Ser. No. 09/829,708 filed on Apr. 10, 2001 which is a continuation of U.S. patent application Ser. No. 09/048,701 filed on Mar. 26, 1998 now U.S. Pat. No. 6,213,895. FIELD OF THE INVENTION [0002] The present invention relates to golf balls and, more particularly, to improved golf balls comprising a unique dual core configuration. The improved golf balls provide for enhanced distance and durability properties. BACKGROUND OF THE INVENTION [0003] A number of two-piece (a solid resilient center or core with a molded cover) and three-piece (a liquid or solid center, elastomeric winding about the center, and a molded cover) golf balls have been produced. The different types of materials utilized to formulate the cores, covers, etc. of these balls dramatically alters the balls' overall characteristics. In addition, multi-layered covers containing one or more ionomer resins have also been formulated in an attempt to produce a golf ball having the overall distance, playability and durability characteristics desired. [0004] Despite the great number of materials and combinations of materials utilized in prior art golf balls, there still remains a need for an improved golf ball exhibiting superior properties. [0005] These and other objects and features of the invention will be apparent from the following summary and description of the invention, the drawings and from the claims. SUMMARY OF THE INVENTION [0006] The present invention addresses the previously noted needs for an improved golf ball and provides, in a first aspect, a golf ball comprising a dual core assembly and a cover layer assembly disposed about the dual core assembly. The dual core assembly includes a center component and a core layer disposed about the center core component. The center component includes a thermoset material, and the core layer comprises a thermoplastic material. The cover layer assembly includes an inner cover layer and an outer cover layer disposed on the inner cover layer. The inner and outer cover layers exhibit particular combinations of Shore D hardness. [0007] In another aspect, the present invention provides a golf ball comprising a dual core having a center component, a core layer disposed about the center component, and a single cover layer disposed about the dual core. The center component of the dual core comprises a thermoset material, and the core layer comprises a thermoplastic material. The single cover layer exhibits a Shore D hardness of from about 40 to about 80. [0008] In a further aspect, the present invention, provides a golf ball comprising a dual core which includes a center component and core layer disposed about the center component. The golf ball further includes a cover layer assembly disposed about the dual core. The center component of the dual core includes a thermoset material, and the core layer comprises a thermoplastic material. [0009] In yet another aspect, the present invention provides a golf ball comprising a dual core having a center component and a core layer disposed about the center component, and a cover layer disposed about the dual core. The center component and the core layer both comprise a thermoplastic material. [0010] In a further aspect, the present invention provides a golf ball comprising a dual core assembly which includes a center component and a core layer disposed about the center component. The golf ball further includes a dual cover assembly disposed on the dual core assembly. The dual cover assembly includes an inner cover layer and an outer cover layer disposed on the inner cover layer. The outer cover layer includes a plurality of dimples, and the inner cover layer and/or the outer cover layer include a first ionomer having 16 weight percent or less acid. And at least one of the inner and outer cover layer includes a second ionomer having more than 16 weight percent acid. [0011] In a further aspect, the present invention provides a golf ball comprising a dual core assembly that includes a center core component and a core layer disposed about the center core component. The golf ball further comprises a cover layer disposed about the dual core assembly in which the cover layer comprises a polyurethane material. [0012] Moreover, the present invention provides a golf ball comprising a dual core assembly which includes a center core component and a core layer disposed about the center core component. The golf ball additionally includes a dual cover assembly disposed on the dual core assembly. The cover assembly includes an inner cover layer having a Shore D hardness of 70 or more and an outer cover layer having a Shore D hardness of 45 or less. [0013] Furthermore, in a still further aspect, the present invention provides a golf ball comprising a dual core assembly having a center core component and a core layer disposed about the center core component. The golf ball further comprises a cover layer disposed about the dual core assembly in which the cover layer includes an acrylic acid based high acid ionomer. That ionomer is neutralized with one or more sodium, potassium, lithium, zinc, magnesium, manganese, calcium, and/or nickel cations. [0014] The present invention also provides in a still further aspect, a golf ball comprising a multi-layer core assembly including a center core component, a first core layer disposed on the core component, and a second core layer disposed on the first core layer. The golf ball further comprises a cover layer disposed on the multi-layer core assembly. [0015] Still further, the present invention provides in another aspect, a golf ball comprising a dual core assembly including a center core component and a core layer disposed on the center core component. The golf ball further comprises a cover layer disposed on the dual core assembly such that the cover layer includes a thermoplastic elastomer. [0016] In yet another aspect, the present invention provides a golf ball comprising a dual core assembly that comprises a center core component and a core layer disposed on the center core component. The center core component includes a thermoset material and the core component includes a thermoplastic material. The golf ball further comprises a multi-layer cover assembly disposed on the dual core assembly such that the multi-layer cover assembly includes an inner cover layer and an outer cover layer.
