1. A folding creeper comprising:a first unit including a wheel side, a pair of opposed sides, and at least two caster wheels coupled to said wheel side; a second unit comprising a wheel side, a pair of opposed sides, and at least two caster wheels coupled to said wheel side, a hinge member including at least one caster, said hinge member connecting said first unit and second unit enabling the first unit and second unit to be manually moved between an open position and a closed position; one caster wheel coupled to said first unit being substantially aligned with one caster wheel coupled to said second unit, and said caster wheel coupled to said hinge member being non-aligned with said aligned wheels coupled to said first unit and said second unit a lock that retains said first unit and said second unit coplanar when the creeper is in the open position, where said lock comprises: a plate member with a hole disposed there through and including a post element having a first end and a second end that projects through the plate member; and a fastener connected to the second end of the post element that upon being unfastened allows the plate member to be manually rotated and upon fastening prevents the plate member from being rotated. 2. A foldable creeper that is capable of supporting a person comprising:a seat support including a base side, an inner end, and at least one caster disposed on said base side; a back support including a base side, an inner end, and at least one caster disposed on said base side; and a first connector and a second connector, each connector including a lower surface, a first end, a second end, and at least one caster coupled to said lower surface; said first ends of each of said first and second connectors being hingedly coupled to said seat support at or near said inner end of said seat support, and said second ends of each of said first and second connectors being hingedly coupled to said back support at or near said inner end of said back support, whereby the back support and seat support are manually moveable between an open position and a closed position, a first lock is attached to the first connector and a second lock attached to the second connector, said first and second locks each having a lock position that retains said seat support and said back support coplanar when the creeper is in an open position and an unlock position that enables said seat support and said back support to be manually moved into a closed position, where each of said first lock and second lock comprises: a plate member that is fastened to the connector in a manner enabling said plate member to be loosened and tightened, when said plate member is tightened and in the locked position, said plate overlaps the inner ends of the seat support and the back support to maintain the seat support and the back support coplanar, and when said plate member is loosened and rotated, the seat support and the back support are enabled to be manually moved into substantially parallel planes. 3. A foldable creeper that is capable of supporting a person comprising:a back support including a pair of spaced apart, longitudinally oriented, opposed rail members that are coupled together, each of said rail members having an inner end and an outer end, a bottom surface, a top side, a caster coupled to each of said bottom surfaces of said longitudinal rail members at the outer end and no casters attached to said inner end, and a cushion member; a seat support including a pair of spaced apart longitudinally oriented, opposed rail members that are coupled together, each of said rail members having an inner end and an outer end, a bottom surface, a caster coupled to each of said bottom surfaces at the outer end and no casters attached to said inner end, and a cushion member; and a connector that attaches the seat support and back support together, said connector including, a pair of U-shaped hinge members, each U-shaped hinge member including, a base having an upper surface, a lower surface, and a pair of opposed ends, a caster attached to the lower surface, a pair of sidewalls that extend from the upper surface of the base, and beyond the opposed ends of said base, and a pair of hinges, each hinge extending between said sidewalls nearby each one of said opposed ends, each of said inner ends of said longitudinal rail members of said back support being coupled to one of said hinges at one of said opposed ends, each of said inner ends of said longitudinal rail members of said seat support being coupled to the other said pair of hinges at the other of said opposed ends, said back support being rotatable in an arc about said one hinge from an open position where said back support is coplanar with said seat support to a closed position where said back support is rotated substantially ninety degrees towards said seat support, and said seat support being rotatable in an arc about said other hinge from an open position where said seat support is coplanar with said back support to a closed position where said seat support is rotated substantially ninety degrees towards said back support. 4. The creeper of claim 3 further comprising an adjustable headrest, said headrest including:a head support member coupled to said back support member, that is capable of supporting the weight of a human head; and an adjustor that adjusts the height and the angle of inclination of said head support relative to said back supporting member. 5. A foldable creeper that is capable of supporting a person comprising:a back support including a pair of spaced apart, longitudinally oriented, opposed substantially parallel, rail members that are coupled together, each of said back support rail members having an inner end and an outer end, each of said inner ends of the back support rail members being indented with respect to their outer ends, and at or near each of the outer ends of the back support rail members a caster attached thereto, a seat support including a pair of spaced apart, longitudinally oriented, opposed substantially parallel, rail members that are coupled together, each of said seat support rail members having an inner end and an outer end, each of said inner ends of the seat support rail members being indented with respect to their outer ends, and at or near each of the outer ends of the seat support rail members a caster wheel attached thereto, said inner ends of the back support rail members being aligned and juxtaposed with inner ends of the seat support rail members, a first connector attaching one juxtaposed inner end of one back support rail member to the aligned juxtaposed inner end of one seat support rail member, and a second connector attaching one juxtaposed inner end of the other back support rail member to the aligned juxtaposed inner end of the other seat support rail member, said first and second connectors being pivotably attached to the inner ends to enable the back support and seat support to be folded inward towards each other and outward into a substantially common plane, and each said first and second connector including a caster that is positioned between the back support and seat support when folded inward towards each other. 6. A folding creeper comprising:a seat support having an inner end and an outer end including at least one caster wheel, a back support having an inner end and an outer end and including at least one caster wheel, said seat and back supports being aligned longitudinally with their respective inner ends being attached by a hinge assembly including a caster wheel, said hinge assembly enabling the seat and back supports to be manually moved between an open position and a closed position, and a lock connected to the hinge assembly having a lock position that retains the seat and back supports coplanar when the creeper is in the open position and an unlock position that enables the seat and back supports to be manually moved into a closed position, said lock including a plate member that is fastened to the hinge assembly in a manner enabling said plate member to be loosened and tightened, when said plate member is tightened and in the locked position, said plate overlaps the inner ends of the seat and back supports to maintain the seat support and the back support substantially coplanar, and when said plate member is loosened and rotated, the seat support and the back support are enabled to be manually moved into substantially parallel planes.
