I claim: 1. A convertible luggage device for transportation of items along a transportation surface, comprising: a main body having a long side and at least one short side, the main body including a compartment for storage, the compartment being capable of being opened and closed to retain items within the compartment; a handle and means for connecting the handle to the main body; and a first pair of wheels and a second pair of wheels and means for mounting the first pair of wheels to the main body for providing the first pair of wheels with, a first retracted position wherein the first pair of wheels include a portion which extends beyond both the long side and the at least one short side of the main body such that the luggage device can be rolled across a transportation surface with the long side being substantially vertical to the transportation surface and a second extended position wherein the first pair of wheels is extended and positioned further from the long side of the body than when in the first position; wherein the luggage device accomplishes storing and retaining items in the compartment when the long side of the luggage device is rolled along the transportation surface. 2. A convertible luggage device of claim 1, wherein the first pair of wheels are retractable and ejectable and activation of the handle accomplishes retraction and ejection of the first pair of wheels. 3. A convertible luggage device of claim 1, the handle further including a brake system. 4. A convertible luggage device of claim 3, wherein, the brake system operates to control rotation of at least one of the second pair of wheels. 5. A convertible luggage device of claim 4, the brake system further including a cable attached to a pulley configured within a tube defining the handle. 6. A convertible luggage device of claim 5, the brake system further including a compression brake arrangement that cooperates with the pulley and cable. 7. A convertible luggage device of claim 6, the brake system further including a brake handle operatively connected to the brake cable, activation of the brake handle accomplishing deactivation of the brake. 8. A convertible luggage device of claim 1, further comprising a basket assembly connected to the long side of the main body. 9. A convertible luggage device of claim 8, the basket assembly defining a generally rectangular space with an open top. 10. A convertible luggage device of claim 9, the basket assembly having walls defined by netting. 11. A convertible luggage device of claim 1, further comprising a strapping system for engaging a child car safety seat. 12. A convertible luggage device of claim 1, further comprising a first zipper accessible compartment that provides access to an interior of the main body. 13. A convertible luggage device of claim 12, further comprising a second zipper accessible compartment that is configured to receive convertible structure of the luggage device. 14. A convertible luggage device of claim 1, wherein the handle includes structure that automatically locks at least one wheel when the handle assembly is pivoted into a first position. 15. A convertible luggage device of claim 1, further comprising a force activated compression brake. 16. The convertible luggage device of claim 1, wherein at least one wheel of the first pair of wheels includes a second portion which overlaps or is contained within boundaries defined by the long side and the at least one short side when the first pair of wheels are in the first retracted position. 17. The convertible luggage device of claim 1, further comprising means for mounting the second pair of wheels to the main body for providing the second pair of wheels with a fully retracted position and an ejected position, wherein the handle is pivotably connected to the main body and operatively connected to the first pair of wheels and second pair of wheels such that activation of the handle causes the first pair of wheels to move from the first retracted position to the second extended position and causes the second pair of wheels to move from the fully retracted position to the ejected position. 18. The convertible luggage device of claim 17, wherein when the first pair of wheels are in the second extended position and the second pair of wheels are in the ejected position, the luggage device can be rolled on the first and second pairs of wheels with the long side parallel to the transportation surface. 19. The convertible luggage device of claim 18, further comprising a pivot point, an L-shaped bracket rigidly connected to the handle and including a locking wedge projecting therefrom, and a rotating arm including a mating structure for receiving the locking wedge, the L-shaped bracket and rotating arm being rotatably connected to the pivot point. 20. The convertible luggage device of claim 19, further comprising: a guide member fixed to the main body; and a tubular extension member including a first end pivotably connected to the L-shaped bracket and a second end portion housing a spring biased brake member, translation of the tubular extension member being controlled by the guide member.
