What is claimed is: 1. A method of closing, sealing and dressing a wound with an adhesive applicator comprising a body with an internal reservoir, adhesive disposed in the internal reservoir and an opening between the internal reservoir and the exterior of the body; a sponge disposed over the opening; a slotted tip nozzle disposed over the sponge; and a small orifice tip nozzle disposed over the slotted tip nozzle; comprising: closing the wound by applying small drops of adhesive to the wound, the small drops being applied by forcing the adhesive from the internal reservoir through the sponge, through the slotted tip nozzle and then through the small orifice tip nozzle; removing the small orifice tip nozzle; sealing the wound by applying a line of adhesive to the wound with the slotted tip nozzle; removing the slotted tip nozzle; and dressing the wound by applying further adhesive to the wound with the sponge. 2. The method of claim 1, wherein forcing the adhesive from the internal reservoir through the sponge, through the slotted tip nozzle and then through the small orifice tip nozzle by squeezing on the body of the applicator. 3. The method of claim 1, further comprising: adjusting the width of the line of adhesive applied by the slotted tip nozzle by rotating the applicator, thereby rotating the slotted tip nozzle. 4. The method of claim 1, wherein the adhesive is a medical adhesive. 5. The method of claim 4, wherein the medical adhesive is a cyanoacrylate ester, in monomeric form, represented by formula I: where R is selected from the group consisting of: alkyl of 1 to 10 carbon atoms, alkenyl of 2 to 10 carbon atoms, cycloalkyl groups of from 5 to 8 carbon atoms, phenyl, 2-ethoxyethyl, 3-methoxybutyl, and a substituent of the formula: wherein each R' is independently selected from the group consisting of: hydrogen and methyl, and R" is selected from the group consisting of: alkyl of from 1 to 6 carbon atoms, alkenyl of from 2 to 6 carbon atoms, alkynyl of from 2 to 6 carbon atoms, cycloalkyl of from 3 to 8 carbon atoms, aralkyl selected from the group consisting of benzyl, methylbenzyl and phenylethyl, phenyl, and phenyl substituted with 1 to 3 substituents selected from the group consisting of hydroxy, chloro, bromo, nitro, alkyl of 1 to 4 carbon atoms, and alkoxy of from 1 to 4 carbon atoms. 6. An applicator for closing, sealing and dressing a wound with liquid adhesive comprising a body with an internal reservoir capable of containing said liquid adhesive, a liquid adhesive-communicating opening between the internal reservoir and the exterior of the body; a liquid adhesive-permeable sponge disposed over the opening; a slotted tip nozzle removably disposed over the sponge; and a small orifice tip nozzle removably disposed over the slotted tip nozzle; the applicator permitting; closure of the wound by applying small drops of the liquid adhesive to the wound to produce a closed wound, the small drops provided by passing a first portion of liquid adhesive from the internal reservoir, through the opening, through the sponge, through the slotted tip nozzle and finally through the small orifice tip nozzle to the wound: removal of the small orifice tip nozzle to form an applicator without a small orifice tip nozzle; the applicator without a small orifice tip nozzle permitting; sealing of the closed wound by applying a line of the liquid adhesive to the closed wound to produce a sealed wound, the line provided by passing a second portion of liquid adhesive from the internal reservoir, through the opening, through the sponge, and finally through the slotted tip nozzle to the closed wound: and removal of the slotted tip nozzle to form an applicator without a small orifice tip nozzle or a slotted tip nozzle, the applicator without a small orifice tip nozzle or a slotted tip nozzle permitting; dressing of the sealed wound by applying a layer of the liquid adhesive to the closed wound to produce a dressed wound; the layer provided by passing a third portion of liquid adhesive from the internal reservoir, through the opening, and finally through the sponge to the sealed wound. 7. The adhesive applicator of claim 6, wherein the small orifice tip nozzle is releasably attached to the slotted tip nozzle. 8. The adhesive applicator of claim 6, wherein the small orifice tip nozzle is releasably attached to the body. 9. The adhesive applicator of claim 6, wherein the body is such that squeezing on the body forces contents of the internal reservoir out through the opening in the applicator body. 10. The adhesive applicator of claim 6, further comprising: a medical liquid adhesive in the internal reservoir. 11. The adhesive applicator of claim 10, wherein the medical adhesive is a cyanoacrylate ester, in monomeric form, represented formula I: where R is selected from the group consisting of: alkyl of 1 to 10 carbon atoms, alkenyl of 2 to 10 carbon atoms, cycloalkyl groups of from 5 to 8 carbon atoms, phenyl, 2-ethoxyethyl, 3-methoxybutyl, and a substituent of the formula: wherein each R' is independently selected from the group consisting of: hydrogen and methyl, and R" is selected from the group consisting of: alkyl of from 1 to 6 carbon atoms, alkenyl of from 2 to 6 carbon atoms, alkynyl of from 2 to 6 carbon atoms, cycloalkyl of from 3 to 8 carbon atoms, aralkyl selected from the group consisting of benzyl, methylbenzyl and phenylethyl, phenyl, and phenyl substituted with 1 to 3 substituents selected from the group consisting of hydroxy, chloro, bromo, nitro, of alkyl 1 to 4 carbon atoms, and alkoxy of from 1 to 4 carbon atoms. 12. The adhesive applicator of claim 6, wherein the nozzle of the slotted tip nozzle has a width of between ⅓ and ⅔ of the width of the sponge.
