We claim: 1. An electric stapler comprising: a housing having an exterior, an interior, a front end, a rear end, a top, and a bottom, wherein said housing has a slot for receiving items to be stapled at said front end; a stapling mechanism contained within said housing, said stapling mechanism comprising a staple carriage accommodating a supply of U-shaped staple pins arranged in a sheet-like row in a groove slidable toward a staple punching outlet at a front end of said groove, a staple biasing means within said staple carriage for urging said staple pins toward said staple punching outlet, a punching arm having a staple punching plate at a front end thereof, wherein said punching arm is vertically movably supported to punch out said staple pins in said staple carriage one after another through the staple punching outlet, a matrix anvil for bending a staple pin punched out through said staple outlet, an arm drive means including an electric motor for driving said punching arm up and down, a control circuit for controlling the operation of said motor, and means for supplying electricity to power said motor; a manually operated power switch controlled by a power button on the exterior of said housing; and a manually actuated reverse switch that causes that motor to operate in the reverse direction in order to clear staple jams, wherein said manually operated power switch must be actuated in order to cause said motor to operate to drive a leading staple pin in said staple carriage into an item to be stapled. 2. The stapler of claim 1, further comprising a stop switch contained within the housing that automatically stops the motor when a single stapling operation has been completed. 3. The stapler of claim 1, wherein the reverse switch is accessible through the bottom of the housing. 4. The stapler of claim 1, wherein the reverse switch is mechanically linked to the staple carriage, such that actuation of said reverse switch when there is no staple jam releases the staple carriage in order to allow access to said staple carriage for replenishing the supply of staple pins. 5. The stapler of claim 1, further comprising a paper-sensing switch having a paper-sensing arm vertically disposed within the slot such that a paper inserted into said slot will press against said paper-sensing arm, actuating said paper-sensing switch, wherein said paper-sensing switch and said manually operated power switch must be actuated in order to cause the motor to operate to drive a leading staple pin in said staple carriage into an item to be stapled. 6. The stapler of claim 5, wherein the control circuit is designed to allow repeated performance of a stapling function as long as the paper-sensing switch is closed, without any need for opening and reclosing said paper-sensing switch between stapling operations. 7. The stapler of claim 6, wherein said stapler is enclosed in a sealed package having a means for momentarily operating said device while the device is inside the package, said package further comprising means for continuously maintaining the paper-sensing switch in a closed position in order to permit repeated activation of the motor. 8. The stapler of claim 1, wherein the means for providing electricity to the motor comprises a compartment in said housing for holding batteries. 9. The stapler of claim 8, wherein the means for providing electricity to the motor further comprises an electric power cord and adapter that can be plugged into a jack on the stapler in order to deliver alternating current from an electrical outlet to said motor. 10. The stapler of claim 1, wherein the means for providing electricity to the motor comprises an electric power cord that can be plugged into an electrical outlet in order to deliver alternating current to said motor. 11. The stapler of claim 1, wherein the housing further comprises a raised collar around the power button. 12. The stapler of claim 1, wherein the power button is disposed on the top and toward the front of the housing. 13. The stapler of claim 1, further comprising a loop for hanging said stapler. 14. The stapler of claim 1, wherein said stapler is enclosed in a sealed package having a means for momentarily operating said device while the device is inside the package. 15. An electric stapler comprising: a housing having an exterior, an interior, a front end, a rear end, a top, and a bottom, wherein said housing has a slot for receiving items to be stapled at said front end; a stapling mechanism contained within said housing, said stapling mechanism comprising a staple carriage accommodating a supply of U-shaped staple pins arranged in a sheet-like row in a groove slidable toward a staple punching outlet at a front end of said groove, a staple biasing means within said staple carriage for urging said staple pins toward said staple punching outlet, a punching arm having a staple punching plate at a front end thereof, wherein said punching arm is vertically movably supported to punch out said staple pins in said staple carriage one after another through the staple punching outlet, a matrix anvil for bending a staple pin punched out through said staple outlet, an arm drive means including an electric motor for driving said punching arm up and down, and a control circuit for controlling the operation of said motor; a battery compartment in the rear of said housing for holding batteries to supply electricity to power said motor; a manually operated power switch controlled by a power button on the exterior of said housing, said housing forming a raised collar surrounding said power button; a paper-sensing switch having a paper-sensing arm vertically disposed within the slot such that a paper inserted into said slot will press against said paper-sensing arm, actuating said paper-sensing switch; a stop switch contained within said housing that automatically stops said motor when a single stapling operation has been completed; a manually actuated reverse switch that causes said motor to operate in the reverse direction in order to clear staple jams; a loop for hanging said stapler; characterized in that both said paper-sensing switch and said power switch must be actuated before the motor operates to drive a leading staple pin in said staple carriage into an item to be stapled. 16.
