1. An adjustable self-closing fence hinge system, the hinge system comprising: a base plate attachable to a fence post, the base plate comprising a first wall mountable to the fence post and a pair of vertically spaced apart and aligned first hinge mounts extending outwardly from the first wall;a swing arm attachable to a fence gate, the swing arm comprising a second wall mountable to the gate;a hinge mounted to the base plate and the swing arm for hingedly connecting the base plate and the swing arm, the hinge comprising: a hinge housing vertically oriented and rotatably mounted to the first hinge mounts,an extension member having a first portion connected to the hinge housing and a second portion mounted to the swing arm;a spring located within the hinge housing, the spring having a first end and an opposite second end, the second end of the spring being fixed relative to the hinge housing, anda spring adjustment system, the spring adjustment system comprising: a pin having a head including a plurality of projections about a circumference of the head and an opposite end of the pin spaced from the head, the pin positioned to cooperate with the spring so that the first end of the spring is fixed relative to the head of the pin so that when the head of the pin is rotated the first end of the spring also rotates,a fastener removably positionable adjacent the opposite end of the pin, anda first pin retainer fixedly located adjacent an end of the housing and including a bore configured to receive the head of the pin, the bore including a plurality of recesses configured to receive the projections of the head of the pin,wherein tension of the spring is fixed when the pin head is seated in the bore of the pin retainer with the projections of the head of the pin received in the recesses of the bore, andwherein tension of the spring is adjustable by removing the fastener from the opposite end of the pin and withdrawing the projections of the head from engagement with the recesses of the bore of the first pin retainer, then rotating the head of the pin to wind or unwind the spring to adjust the tension of the spring, and then by installing the fastener onto the opposite end of the pin and positioning the projections of the head into engagement with the recesses of the bore of the first pin retainer, thereby fixing the tension of the spring at the adjusted tension. 2. The fence hinge system of claim 1, wherein the hinge housing is tubular. 3. The fence hinge system of claim 2, wherein the second end of the spring is fixed relative to the hinge housing by positioning the second end of the spring within a notch defined on the housing. 4. The fence hinge system of claim 1, wherein the head of the pin includes an aperture and the first end of the spring is fixed relative to the head of the pin by passing the first end of the spring into the aperture of the head of the pin. 5. The fence hinge system of claim 1, wherein the spring is an elongate torsion spring and the spring surrounds portions of the pin. 6. The fence hinge system of claim 1, further comprising a second pin retainer fixedly located adjacent an opposite end of the housing and including a through bore for passage of the pin and an enlarged exterior recess configured to receive the opposite end the pin and the fastener when it is installed onto the opposite end of the pin. 7. The fence hinge system of claim 1, wherein the first pin retainer is fixedly located adjacent the housing by a second fastener extending between the base plate and the first pin retainer. 8. The fence hinge system of claim 1, wherein the spring tension may be adjusted to substantially untension the spring so that the hinge system is no longer self-closing. 9. An adjustable self-closing hinge, the hinge comprising: a hinge housing rotatably mountable relative to a body by a hinge mount; a spring located within the hinge housing, the spring having a first end and an opposite second end, the second end of the spring being fixed relative to the hinge housing; anda spring adjustment system, the spring adjustment system comprising: a pin having a head including a plurality of projections about a circumference of the head and an opposite end of the pin spaced from the head, the pin positioned to cooperate with the spring so that a first end of the spring is fixed relative to the head of the pin so that when the head of the pin is rotated the first end of the spring also rotates,a fastener removably positionable on the opposite end of the pin, anda first pin retainer fixedly located adjacent an end of the housing and including a bore configured to receive the head of the pin, the bore including a plurality of recesses configured to receive the projections of the head of the pin,wherein tension of the spring is fixed when the pin head is seated in the bore of the pin retainer with the projections of the head of the pin received in the recesses of the bore, andwherein tension of the spring is adjustable by removing the fastener from the opposite end of the pin and withdrawing the projections of the head from engagement with the recesses of the bore of the first pin retainer, then rotating the head of the pin to wind or unwind the spring to adjust the tension of the spring, and then by installing the fastener onto the opposite end of the pin and positioning the projections of the head into engagement with the recesses of the bore of the first pin retainer, thereby fixing the tension of the spring at the adjusted tension. 10. The fence hinge system of claim 9, wherein the second end of the spring is fixed relative to the hinge housing by positioning the second end of the spring within a notch defined on the housing. 11. The fence hinge system of claim 9, wherein the head of the pin includes an aperture and the first end of the spring is fixed relative to the head of the pin by passing the first end of the spring into the aperture of the head of the pin. 12. An adjustable hinge, the hinge comprising: a hinge housing rotatably mountable relative to a body;a spring located within the hinge housing, the spring having a first end and an opposite second end, the second end of the spring being fixed relative to the hinge housing; anda spring adjustment system, comprising: a pin having a head including a plurality of projections about a circumference of the head and an opposite end of the pin spaced from the head, the pin positioned to cooperate with the spring so that a first end of the spring is fixed relative to the head of the pin so that when the head of the pin is rotated the first end of the spring also rotates, anda pin retainer fixedly located relative to the housing and including a bore configured to receive the head of the pin, the bore including a plurality of recesses configured to receive the projections of the head of the pin,wherein tension of the spring is fixed when the pin head is seated in the bore of the pin retainer with the projections of the head of the pin received in the recesses of the bore, andwherein tension of the spring is adjustable by withdrawing the projections of the head from engagement with the recesses of the bore of the pin retainer, then rotating the head of the pin to wind or unwind the spring to adjust the tension of the spring, and then positioning the projections of the head into engagement with the recesses of the bore of the pin retainer, thereby fixing the tension of the spring at the adjusted tension.
