1. A foldable creeper that is capable of supporting a person comprising:a seat support including a base side, an inner end and an outer end, and at least one pair of casters disposed on said base side at or near the outer end;a back support including a base side, an inner end and an outer end, and at least one pair of casters disposed on said base side at or near the outer end,said back support and seat support being hingedly connected together at their respective inner ends to be manually moveable between an open position where said seat support and said back support are substantially coplanar and a closed position where said seat support and said back support are substantially parallel, anda manually operable lock member mounted to rotate between a lock position that retains said seat and back supports coplanar when in the open position and an unlock position that enables said seat and back supports to be manually moved into the closed position, said lock member in the lock position overlapping the inner ends of the seat support and the back support to maintain the seat support and the back support coplanar.2. The foldable creeper of claim 1 where said seat support and said back support each have a support side, and when the creeper is in said closed position, said support sides face away from each other and said casters are disposed between said seat and said back supports.3. A folding creeper comprising:first and second longitudinally oriented units,the first unit including a bottom and a top, an inner end and an outer end, a first side and a second side between said inner and outer ends, and at least two casters coupled to said bottom at or near the outer end, with one first unit caster near the first side of the first unit and the other first unit caster near the second side of the first unit;the second unit including a bottom and a top, an inner end and an outer end, a first side and a second side between said inner and outer ends, and at least two casters coupled to said bottom at or near the outer end thereof with one second unit caster near the first side of the second unit and the other second unit caster near the second side of the second unit;a hinge assembly attached to the inner ends of the first and second units to connect said first and second units in a manner to enable said units to be folded longitudinally moving from an open position into a closed position with the tops of the units facing away from each other,said hinge assembly including at least two casters, one hinge assembly caster being positioned inward of said first sides of the units, and the other hinge assembly caster being positioned inward of said second sides of the units, said hinge assembly casters being non-aligned longitudinally with the casters coupled to said first and second units.4. The foldable creeper of claim 3 including a plate member that is mounted to the hinge assembly to rotate between a lock position and an unlock position and tightened in the lock position and loosened to rotate into the unlock position.5. The foldable creeper of claim 4 where said plate member, when tightened and in the locked position, overlaps the inner ends of the units.6. The foldable creeper of claim 3 where portions of said sides of the units near the inner ends are inwardly indented.7. A foldable creeper that is capable of supporting a person comprising:a back support including a pair of spaced apart, longitudinally oriented, substantially parallel, rail members, 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,a caster attached at or near each of the outer ends of the back support rail members,a seat support including a pair of spaced apart, longitudinally oriented, substantially parallel, rail members, 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,a caster attached at or near each of the outer ends of the seat support rail members,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, anda 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 connectors including a caster.8.
