What is claimed is: 1. A waste collection device, comprising: a body including a housing defining an opening which allows an open end of an associated bag to be folded thereover, said body supporting a closed end of said associated bag; a spool rotatably connected to said body and removably connected to said associated bag; and a driving mechanism connected to said spool for selectively rotating said spool such that the associated bag is wound on said spool thereby pulling said associated bag into said housing. 2. The waste collection device of claim 1 wherein said housing comprises a U-shaped base portion having a substantially flat lower wall and a pair of spaced apart side walls extending upward from said lower wall. 3. The waste collection device of claim 2 wherein said body includes a handle that is foldable between a folded-down position adjacent said lower wall and a folded-open position wherein said handle extends away from said lower wall. 4. The waste collection of claim 3 wherein at least one preselected position is provided between said folded-down position and said folded-open position, and wherein at least one of said handle and said housing includes at least one movable element which is received in a recess defined in the other of said one of said handle and said housing for holding said handle in said at least one preselected position. 5. The waste collection device of claim 1 wherein said driving mechanism comprises a motor. 6. The waste collection device of claim 5 further comprising: a frame member movably mounted adjacent said opening of said housing that together with said housing forms said opening, said frame member being movable between an open position and a closed position; and an actuator member disposed on said body for operating at least one of said motor and said movable frame member. 7. The waste collection device of claim 6 wherein said actuator member is a two-function actuator member that electrically connects said motor to a power source upon initial depression and mechanically moves said frame member toward said closed position upon further depression. 8. The waste collection device of claim 7 further including at least one lever connected to said frame member to move said frame member upon depression of said actuator member, said at least one lever connected to said frame member at a location offset relative to an axis defined through a pivotal connection of said frame member to said housing, depression of said actuator member causing movement of said at least one lever to move said frame member toward said closed position, unless said frame member is positioned in said closed position. 9. The waste collection device of claim 6 further comprising a spring for urging said movable frame member towards one end position in relation to said housing. 10. The waste collection device of claim 1 further including: a frame member movably mounted adjacent said opening of said housing that together with said housing forms said opening, said frame member being movable between an open position and a closed position; and an actuator member disposed on said body for operating said movable frame member, said actuator member selectively engaging at least one lever connected to said frame member to move said frame member upon depression of said actuator member, said at least one lever being connected to said frame member at a location offset relative to an axis defined through a pivotal connection of said frame member to said housing, depression of said actuator member causing movement of said at least one lever to move said frame member toward said closed position. 11. The waste collection device of claim of claim 9 further comprising a spring wherein said frame member is urged by said spring toward said open position when said frame member is in an intermediate position between said open position and said closed position. 12. The waste collection device of 9 wherein said frame member is manually movable between said open position and said closed position, wherein depression of said actuator member only moves said frame member to an intermediate position between said open position and said closed position. 13. The waste collection device of claim 1 wherein said spool includes an outer barrel member and an inner barrel member telescopingly received within said outer barrel member. 14. The waste collection device of claim 13 wherein at least one of said outer member and said inner member includes at least one tab and the other of said at least one of said outer member and said inner member includes at least one corresponding aperture into which said at least one tab is received for limiting relative rotation between said inner and outer members. 15. The waste collection device of claim 14 wherein said at least one tab includes a pair of diametrically opposed tabs and said at least one aperture includes a pair of diametrically opposed slots for guiding telescopic movement between said inner and outer members. 16. The waste collection device of claim 13 further comprising a spring which is disposed between an innermost end of said outer barrel member and an end of said inner barrel member that is received in said outer barrel member, wherein said spring urges said inner member toward an elongated position. 17. The waste collection device of claim 13 wherein at least one bag mounting aperture is defined in said outer barrel member and said inner barrel member such that an end of said associated bag can be threaded through said spool and tied off. 18. The waste collection device of claim 1 wherein said spool includes a first end comprising a socket and radially extending teeth which are selectively engageable with a spool gear of said driving mechanism. 19. The waste collection device of claim 1 wherein said body includes a frame member movably mounted adjacent said opening of said housing, said opening being defined by said housing and said frame member when said frame member is in an open position. 20. The waste collection device of claim 1 wherein said frame member is U-shaped and together with said housing forms said opening, said frame member being movable between a fully open position wherein said opening is fully defined and a fully closed position wherein said frame member nests around said housing for compact storage. 21. A waste collection device, comprising: a body including a housing defining an opening which allows an open end of an associated bag to be folded thereover, said housing receiving a closed end of said associated bag therein; a spool rotatably connected to said body and removably connected to said associated bag; and a motor selectively connected to said spool for selectively rotating said spool such that the associated bag is wound on said spool thereby pulling said associated bag into said housing. 22. The waste collection device of claim 21 further including a transmission assembly that selectively connects an output of said motor to said spool so said spool is rotated by said motor when said motor is actuated. 23. The waste collection device of claim 22 wherein said transmission assembly includes a motor and gear mounting arrangement which is movably mounted relative to said housing so that it is movable between an engaged position wherein said gear is operatively engaged with said spool so that powered rotation from said motor effects rotation of said spool and a disengaged position wherein said gear is disengaged from said spool allowing manual rotation of said spool, said connection assembly further including a spring urging said motor and gear toward said engaged position and a disengaging knob for manually moving said motor and said gear toward said disengaged position against urging of said spring. 24. The waste collection device of claim 21 wherein said body includes a handle that is movable between a folded-down position and a folded-open position. 25. The waste collection device of claim 24 further comprising a switch which prevents operation of said motor unless said handle is in said folded-open position. 26. A waste collection device, comprising: a body including a U-shaped housing having an open end; a frame member pivotally secured to said housing adjacent said open end, said frame member being movable toward an open position for defining an opening together with said U-shaped housing; a spool rotatably connected to said body at a location spaced from said open end; and a bag having a bag closed end adapted to be secured to said spool and a bag open end adapted to be passed through said housing open end and folded over said housing and said frame member, wherein rotation of said spool winds said bag thereon and pulls said bag open end into said housing open end.
