1. A method of controlling process temperatures in a molding apparatus, said method comprising the steps of: controlling a temperature of a mold member with a heat source; and  arranging an anisotropic diffuser member along a surface of said mold member for distributing heat uniformly from said heat source through said anisotropic diffuser member, wherein said diffuser member includes a fibrous reinforced composite having a plurality of discontinuous fibers each having a respective length, said fibers being arranged in a lay-up with said length of each fiber being discontinuously arranged to achieve a substantially uniform distribution of heat within said diffuser member. 2. The method of controlling process temperatures in a molding apparatus according to  claim 1 , wherein said fibrous composite is a graphite reinforced composite. claim 1 3. The method of controlling process temperatures in a molding apparatus according to  claim 1 , wherein said diffuser member is arranged in a position along an interior surface of a mold cavity of said molding member. claim 1 4. The method of controlling process temperatures in a molding apparatus according to  claim 1 , wherein said diffuser member is arranged in a position along an exterior surface of a mold cavity of said molding member. claim 1 5. A mold assembly for a molding process comprising: a mold member; and  an anisotropic diffuser member, said diffuser member comprising a fibrous composite having a plurality of discontinuous fibers each having a respective length, said fibers being arranged in a lay-up having a plurality of layers of said discontinuous fibers with said length of each fiber being discontinuously arranged to achieve a substantially uniform heat transfer within said diffuser member, and wherein said fibers within each layer of said plurality of layers are co-planar with adjacent fibers within the same layer. 6. A mold assembly for a molding process comprising: a mold member; and  an anisotropic diffuser member, said diffuser member comprising a  fibrous composite having a plurality of discontinuous fibers each having respective length, said fibers arranged in a lay-up with said length of each fiber being discontinuously arranged in a lay-up plane to achieve a substantially uniform heat transfer within said diffuser member, wherein said diffuser member is arranged in a position permitting a rapid transfer of heat along said length of each fiber within say lay-up plane to said mold member. 7. The mold assembly for a molding process according to  claim 6 , wherein said fibrous composite is a graphite reinforced composite. claim 6 8. The mold assembly for a molding process according to  claim 6 , wherein said diffuser member is a diffuser plate. claim 6 9. The mold assembly for a molding process according to  claim 6 , wherein said diffuser member is a thermal coating. claim 6 10. The mold assembly for a molding process according to  claim 6 , wherein said mold member includes a mold cavity, said diffuser member being arranged within said mold cavity. claim 6 11. The mold assembly for a molding process according to  claim 6 , wherein said mold member includes a mold cavity, said diffuser member being arranged alongside said mold cavity. claim 6 12. The mold assembly for a molding process according to  claim 6 , further comprising a heating member. claim 6 13. An anisotropic diffuser plate for a mold assembly, said diffuser plate comprising a fibrous composite having a plurality of discontinuous fibers each having a respective length, said fibers arranged in a lay-up with said length of each fiber being discontinuously arranged in a lay-up plane to achieve a substantially uniform heat transfer within said diffuser member, wherein said diffuser member permits a rapid transfer of heat along said length of each fiber within said lay-up plane. 14. The diffuser plate according to  claim 13 , wherein said fibrous composite is a graphite reinforced composite. claim 13
