1. A wheel and axle system, the system comprising: a. an axle having a longitudinal axis and a wheel-coupling end, the wheel-coupling end having an indentation in the wheel-coupling end substantially concentric with the longitudinal axis; b. a wheel having a rotational axis, and a clearance hole parallel to and offset from the rotational axis of the wheel, the wheel further comprising a hub for insertion into the indentation in the wheel-coupling end of the axle; and c. a fastener, for insertion through the clearance hole for securing the wheel to the axle. 2. A wheel and axle system as claimed in claim 1, wherein the fastener is a threaded bolt. 3. A wheel and axle system, the system comprising: a. an axle having an indentation at a distal end for a wheel hub; b. a lug stud, nonconcentric with the axle, extending from the distal end of the axle; c. a wheel having a rotational axis through a center and a clearance hole to admit the lug stud, the clearance hole offset from the center of the wheel and parallel to the rotational axis; d. a wheel hub, the wheel hub connected to the wheel and disposed within the indentation of the axle; and e. a lug nut for attaching the wheel to the lug stud. 4. A method for attaching a wheel to an axle, the wheel having a rotational axis and a hub centered about the rotational axis and the axle having a longitudinal axis, the method comprising: a. aligning the rotational axis of the wheel with the longitudinal axis of the axle; b. inserting the wheel hub into an indentation in an end of the axle, the indentation substantially concentric with the longitudinal axis of the axle; and c. fastening the wheel to the axle at a point offset from the rotational axis of the wheel. 5. The method of claim 4, wherein the step of fastening the wheel to the axle includes inserting a lug stud, attached to the axle, through a clearance hole in the wheel and securing the lug stud with a lug nut. 6. The method of claim 4, wherein the step of fastening the wheel to the axle includes inserting a bolt through a clearance hole in the wheel and into a threaded hole in the axle. 7. A wheel, the wheel characterized by a rotational axis and a plane of rotation, the wheel comprising: a. a clearance hole parallel to and offset from the rotational axis of the wheel for admission of a fastener; and b. a hub extending about the rotational axis outside the plane of rotation for insertion into an indentation in a wheel-coupling end of an axle, the indentation substantially concentric with the longitudinal axis of the axle. 8. A wheel as claimed in claim 7, wherein the fastener is a threaded bolt. 9. A wheel as claimed in claim 7, wherein the fastener is a lug stud coupled to the indentation of the axle. 10. An axle, the axle characterized by a longitudinal axis, the axle comprising: a. an indentation at a distal end for a wheel hub, the indentation substantially concentric with the longitudinal axis of the axle; and b. a fastener, nonconcentric with the axle, extending from the distal end of the axle for securing a wheel. 11. An axle as claimed in claim 10, wherein the fastener is a lug stud. 12. An axle, the axle characterized by a longitudinal axis, the axle comprising: a. an indentation at a distal end for a wheel hub; and b. a threaded bolt hole parallel to the longitudinal axis of the axle and offset from the longitudinal axis for receiving a bolt to secure a wheel.
