What is claimed is: 1. A tray adapted to be suspended from another implement, wherein the implement has a pair of legs extending non-perpendicular to a ground surface on which the implement is being supported, the tray comprising: a main body portion for holding articles therein; said main body portion including a pair of corner portions and a bottom wall; a neck portion extending from the bottom wall of said main body portion at an angle of at least about 135 degrees from the bottom wall, and further having a width that is less than a width of the main body portion, so that said neck portion may extend between the pair of legs of the implement which the tray is suspended from, and such that the corner portions of the main body portion abut against the legs of the implement and maintain the bottom wall generally parallel to a ground surface on which the implement is resting; a hook portion formed at a distal end of said neck portion, said hook portion shaped to enable it to engage a portion of said implement so that said tray can be suspended from said implement, with said corner portions of the main body portion of said tray abutting the legs of said implement to maintain said main body portion rotationally stable as articles are placed in and removed from said main body portion; and said tray being attachable and removable from said implement without the need for any external tools or independent fastening elements. 2. The tray of claim 1, wherein said main body portion includes a lip formed along an upper edge surface thereof to add structural strength and rigidity to said tray. 3. The tray of claim 1, wherein said neck portion extends from said tray at an angle that is approximately equal to an angle at which the pair of legs, that said tray abuts when suspended from said implement, extend, relative to the ground surface on which said pair of legs are supported. 4. The tray of claim 3, wherein said tray forms an L-shape. 5. The tray of claim 3, wherein said hook portion is fixedly secured to said neck portion. 6. The tray of claim 1, wherein: said implement comprises a ladder; said width of the neck portion is sufficiently narrow to fit between a pair of longitudinal members of said ladder; said hook portion is shaped to engage with a rung of said ladder; and said neck portion and said main body portion cooperate to enable said corner portions of the main body portion to rest against said longitudinal members when said tray is suspended from said rung and said ladder is positioned for use, to thus stabilize said tray against rotational movement while in use suspended from said rung. 7. The tray of claim 1, wherein said main body portion and said neck portion are shaped with a draft that enables said tray to be stacked with additional ones of said tray, when not in use. 8. A tray adapted to be suspended from a chair, where the chair has four metal legs, with a rear pair of the legs being angled to extend non-perpendicular to a ground surface on which said chair is being supported, and having a center section extending perpendicularly between said rear pair of legs, the tray comprising: a main body portion for holding articles therein, the main body portion including a bottom wall and a pair of corner portions; a neck portion extending from the bottom wall of said main body portion at an angle of between about 105-135 degrees, and having a width that is less than a width of the main body portion; a hook portion formed at a distal end of said neck portion, said hook portion shaped to enable it to engage with said center section of said chair so that said tray can be suspended from said chair while resting with said corner portions of the main body portion of said tray abutting said rear pair of legs of said chair, and with said neck portion disposed between the rear pair of legs, to maintain said main body portion rotationally stable as articles are placed in and removed from said main body portion, and to maintain the bottom wall approximately parallel to the ground surface on which the chair is resting; and said tray being attachable and removable from said center section of said chair without the need for any external tools or independent fastening elements. 9. The tray of claim 8, wherein said main body portion and said neck portion are each formed with a draft that enables said tray to be stacked with another said tray, when not in use. 10. The tray of claim 9, wherein said main body portion has an L-shape when viewed in plan, a portion of said main body portion being sized to receive a laptop computer when said laptop computer is positioned on an end thereof and in a closed orientation. 11. The tray of claim 10, wherein said main body portion includes a lip for adding structural strength and rigidity to said main body portion. 12. A tray adapted to be suspended from a chair, where the chair has four metal legs, with a rear pair of the legs being angled to extend non-perpendicular to a ground surface on which said chair is being supported, and said rear pair of legs having a center section extending perpendicularly between said rear pair of legs, the tray comprising: a main body portion for holding articles therein, the main body portion including a bottom wall and a pair of corner portions; a neck portion extending from the bottom wall of said main body portion and forming an integral extension of said main body portion, the neck portion extending at an angle non-perpendicular to the bottom wall; the neck portion having a width less then that of the main body portion, a hook portion formed at a distal end of said neck portion, said hook portion shaped to enable it to engage with said center section of said chair so that said tray can be suspended from said chair while resting with said corner portions of the main body portion of said tray abutting said rear legs of said chair, to maintain said main body portion rotationally stable as articles are placed in and removed from said main body portion and without interfering with the legs of an occupant of said chair, and further such that said bottom wall is maintained generally parallel to the around surface; said main body portion and said neck portion being formed with a draft to permit stacking of said tray with additional ones of said tray for convenient storage; and said tray being attachable and removable from said center section of said chair without the need for any external tools or independent fastening elements. 13. The tray of claim 12, wherein said main body portion includes an integrally formed lip portion along an upper edge thereof for adding structural strength and rigidity to said tray. 14. The tray of claim 12, wherein said neck portion has a width narrower than a spacing of said rear legs of said chair to enable said neck portion to rest between said rear legs when said tray is suspended from said center section. 15. The tray of claim 14, wherein said neck portion includes at least one stiffening rib integrally formed therein. 16. The tray of claim 15, wherein said neck portion includes a pair of stiffening ribs integrally formed therein.
