What is claimed is: 1. A method of decomposing an organic azide, comprising: allowing an organic azide to contact a catalyst that comprises a transition metal halide, wherein the organic azide has the formula R--N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group. 2. A method as recited in claim 1, wherein the transition metal in the transition metal halide can have one or more formal oxidation states. 3. A method as recited in claim 1, wherein the transition metal in the transition metal halide is present in its highest formal oxidation state. 4. A method of decomposing an organic azide, comprising: allowing an organic azide to contact a catalyst that comprises an iron halide or a mixture of iron halide and a second catalyst, wherein the organic azide has the formula R--N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group. 5. A method of decomposing an organic azide, comprising: allowing an organic azide to contact a catalyst that comprises a transition metal chloride, wherein the organic azide has the formula R--N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group. 6. A method as recited in claim 5, wherein the transition metal chloride comprises iron (III) chloride, iron (II) chloride, or a combination of iron (III) chloride and iron (II) chloride. 7. A method of decomposing an organic azide, comprising: allowing an organic azide to contact a catalyst that comprises an iron chloride in combination with a second catalyst, wherein the organic azide has the formula R--N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group. 8. A method of decomposing an organic azide, comprising: allowing an organic azide to contact a catalyst that comprises a metal halide, main group halide, mixed metal-main group halide, or mixture thereof, wherein the organic azide has the formula R--N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group, and wherein the catalyst is dispersed on a support. 9. A method as recited in claim 8, wherein the support comprises a second organic azide decomposition catalyst. 10. A composition of matter comprising: (a) an organic azide having the formula R--N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group; and (b) a catalyst capable of decomposing the organic azide, said catalyst comprising a transition metal halide. 11. A composition of matter as recited in claim 10, wherein the transition metal in the transition metal halide can have one or more formal oxidation states. 12. A composition of matter as recited in claim 10, wherein the transition metal in the transition metal halide is present in its highest formal oxidation state. 13. A composition of matter comprising: (a) an organic azide having the formula R--N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group; and (b) a catalyst capable of decomposing the organic azide, said catalyst comprising an iron halide or a mixture of iron halide and a second catalyst. 14. A composition of matter comprising: (a) an organic azide having the formula R--N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group; and (b) a catalyst capable of decomposing the organic azide, said catalyst comprising a transition metal chloride. 15. A composition of matter as recited in claim 14, wherein the transition metal chloride comprises iron (III) chloride, iron (II) chloride, or a combination of iron (III) chloride and iron (II) chloride. 16. A composition of matter comprising: (a) an organic azide having the formula R--N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group; and (b) a catalyst capable of decomposing the organic azide, said catalyst comprising an iron chloride in combination with a second catalyst. 17. A composition of matter comprising: (a) an organic azide having the formula R--N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group; and (b) a catalyst capable of decomposing the organic azide, said catalyst comprising at least one metal halide, main group halide, mixed metal-main group halide, or mixture thereof; and wherein the catalyst is dispersed on a support. 18. A composition of matter as recited in claim 17, wherein the support comprises a second organic azide decomposition catalyst.
