The invention claimed is: 1. A method of aligning a property for testing in a dynamometer cell, the property having predetermined optimal alignment dimensions, the property defined at least in part by at least one of a motor, engine, and transmission, the method comprising: orienting at least two lasers based at least in part upon the predetermined optimal alignment dimensions to thereby provide a set of target locations; orienting the property such that predetermined locations of the property align with said set of target locations to ensure appropriate property orientation during testing; mounting at least two laser travel cars in a repositionable manner; mounting a respective one of said at least two lasers to each of said at least two laser travel cars in a repositionable manner; calibrating said at least two lasers; securing a dyno cart into a cart receiving station; preparing said dyno cart to receive the property; mounting the property to said dyno cart; and removing said dyno cart from said cart receiving station for delivery to the dynamometer cell. 2. The method of claim 1, wherein said mounting at least two travel cars includes: attaching one of said at least two laser travel cars to a first riser; and attaching the other of said at least two laser travel cars to a second riser, said second riser being generally perpendicularly oriented with respect to said first riser. 3. The method of claim 2, wherein said orienting at least two lasers includes: positioning said respective one of said lasers mounted to said first riser at a first position such that a laser beam emitted therefrom creates a first target point; and positioning said respective one of said lasers mounted to said second riser at a second position such that a laser beam emitted therefrom creates a second target point; wherein said set of target locations is defined at least in part by said first and second target points. 4. The method of claim 3, wherein said mounting a respective one of said at least two lasers to each of said at least two laser travel cars includes: attaching a height gauge to each of said at least two laser travel cars in a repositionable manner; mounting a laser adapter to each of said height gauges; and attaching a respective one of said lasers to each of said laser adapters. 5. The method of claim 4, wherein said calibrating said at least two lasers includes: attaching a first scale having opposing ends to said first riser; attaching a second scale having opposing ends to said dyno cart substantially parallel to said first scale; and orienting said respective one of said lasers mounted to said first riser such that a laser beam emitted therefrom crosses said first scale at a first point and said second scale at a second point, said first and second points being at equal distances from respective ends of said first and second scales. 6. The method of claim 5, wherein said calibrating said at least two lasers further includes: attaching a third scale having opposing ends to said second riser; attaching a fourth scale opposing ends to said dyno cart substantially parallel to said third scale; orienting said respective one of said lasers mounted to said second riser such that a laser beam emitted therefrom crosses said third scale at a third point and said fourth scale at a fourth point, said third and fourth points being at equal distances from respective ends of said third and fourth scales. 7. The method of claim 6, wherein said calibrating said at least two lasers further includes: establishing an absolute zero height position for said at least two lasers. 8. The method of claim 7, wherein said preparing said dyno cart to receive the property includes: attaching at least one cross beam to said dyno cart based at least in part upon the predetermined optimal alignment dimensions. 9. The method of claim 8, wherein said preparing said dyno cart to receive the property further includes: setting at least one support element to a predetermined height based at least in part upon the predetermined optimal alignment dimensions; and attaching said at least one support element to said at least one cross beam based at least in part upon the predetermined optimal alignment dimensions. 10. The method of claim 9, wherein said preparing said dyno cart to receive the property further includes: attaching an engine mount to each of said at least one support elements based at least in part upon the predetermined optimal alignment dimensions. 11. The method of claim 10, wherein said mounting the property to said dyno cart includes: positioning the property such that it is generally vertically adjacent to said at least one support element; orienting the property relative to said dyno cart based at least in part upon the predetermined optimal alignment dimensions; and mounting said property to said engine mount. 12. The method of claim 11, wherein said receiving station includes a receiving portion that is substantially similar to a receiving portion inside the dynamometer cell that is configured to mate with, receive, and secure said dyno cart. 13. A method of carting a property for testing in a dynamometer cell, the property having predetermined optimal alignment dimensions, the property defined at least in part by at least one of a motor, engine, and transmission, the method comprising: mounting a plurality of laser travel cars in a repositionable manner; mounting at least one of a plurality of lasers to each of said plurality of laser travel cars in a repositionable manner; securing a dyno cart into a cart receiving station; calibrating said plurality of lasers; preparing said dyno cart to receive the property; mounting the property to said dyno cart; orienting said plurality of lasers based at least in part upon the predetermined optimal alignment dimensions to thereby provide a set of target locations; and orienting the property such that predetermined locations of the property align with said set of target locations to ensure appropriate property orientation during testing. 14. The method of claim 13, wherein said mounting a plurality of travel cars includes: attaching a first of said plurality of laser travel cars to a first riser; attaching a second of said plurality of laser travel cars to a second riser; attaching a third of said plurality of laser travel cars to a third riser; and attaching a fourth of said plurality of laser travel cars to a fourth riser; wherein said first, second, third and fourth risers are positioned to thereby create a four-sided envelope therebetween. 15. The method of claim 14, wherein said orienting said plurality of lasers includes: positioning a first of said plurality of lasers at a first position relative to said first riser such that a laser beam emitted therefrom creates a first target point; positioning a second of said plurality of lasers at a second position relative to said second riser such that a laser beam emitted therefrom creates a second target point; positioning a third of said plurality of lasers at a third position relative to said third riser such that a laser beam emitted therefrom creates a third target point; and positioning a fourth of said plurality of lasers at a fourth position relative to said fourth riser such that a laser beam emitted therefrom creates a fourth target point; wherein said set of target locations is defined at least in part by said first, second, third and fourth target points. 16.
