A portable hair washing apparatus as described in claim 5, wherein said hair washing support assembly further includes a drainage pipe being mounted to said tank member, and having a main portion, and also having a first end portion being angled relative to said main portion and being disposed through said front wall into said lower compartment of said tank member, and further having a second end portion being angled relative to said main portion and upon which said headrest member is mounted. 7. A portable hair washing apparatus as described in claim 6, wherein said headrest member is generally a basin having a drainage hole disposed through a wall thereof, said headrest member having a boss which is securely mounted in an open second end of said drainage pipe and which has a bore disposed therethrough. 8. A portable hair washing apparatus as described in claim 7, wherein said hair washing assembly further includes a water pump member being disposed in said upper compartment of said tank member, and also includes a conduit being attached to said water pump member and to said water outlet port of said tank member, and further includes a battery being disposed in a battery compartment in said tank member and being connected with wires to said water pump member, and also includes a pump activation switch being connected with wires to said battery, and further includes a spray nozzle being attached to a free end of said semi-rigid hose for spraying water onto a user's hair. 9. A portable hair washing apparatus as described in claim 8, wherein said pump activation switch includes a housing and a foot pedal being depressibly mounted upon said housing. ed to a mattress assembly for use in a sofa sleeper. The mattress assembly has a first mattress that has an inner-spring construction. Disposed above the first mattress is a second mattress that has an air bladder construction. The air bladder of the second mattress has a valve, which is located adjacent the head end of the mattress. The valve is adapted to selectively allow air into and out of the air bladder. The mattress assembly thus provides the combination of an innerspring mattress with an air mattress. The location of the valve allows the air mattress portion to be deflated properly and allows convenient access to the valve for inflation or air pressure adjustment purposes. e corresponding to the nodes; dispatching the questions to selected ones of the plurality of question handlers; receiving responses to the questions from the selected ones of the plurality of question handlers; and providing the responses to the question handlers from which the questions were received. 12. At least one computer-readable media as recited in claim 11, further comprising: detecting when a response provided to a question handler included incorrect information; and re-dispatching at least a subset of the questions in response to detecting the response included incorrect information. 13. A method comprising: associating one or more question handlers with each of a plurality of nodes of a graph representing a program, the plurality of nodes being interconnected via a plurality of links; altering the graph by a question handler corresponding to one of the plurality of nodes adding one or more new nodes to the plurality of nodes; and disallowing any question handler corresponding to one of the plurality of nodes from deleting any of the plurality of nodes. 14. A method as recited in claim 13, further comprising altering the graph by the question handler adding one or more new links to the graph. 15. A method as recited in claim 13, further comprising disallowing any question handler from deleting any of the plurality of links. 16. A method as recited in claim 13, further comprising the question handler receiving a question requesting program code and altering the graph in response to the question. 17. A method as recited in claim 13, further comprising transforming the program into the desired output based at least in part on both the plurality of nodes and the plurality of question handlers. 18. At least one computer-readable memory containing a computer program that is executable by a processor to perform the method recited in claim 13. 19. A method for transforming a program represented as a graph into a desired output, the method comprising: receiving a first plurality of questions from a plurality of question handlers corresponding to a plurality of nodes of the graph; dispatching a second plurality of questions to the plurality of question handlers; receiving responses to the second plurality of questions from the plurality of question handlers; providing responses to the first plurality of questions to the plurality of question handlers; detecting when a response provided to a question handler of the first plurality of question handlers included incorrect information; and re-dispatching at least a subset of the second plurality of questions in response to detecting the response that included incorrect information. 20. A method as recited in claim 19, wherein the re-dispatching at least the subset of the second plurality of questions comprises re-dispatching the question that elicited the response that included incorrect information. 21. A method as recited in claim 19, further comprising maintaining a record of the first plurality of questions, the responses to the first plurality of questions, the second plurality of questions, and the responses to the second plurality of questions. 22. A method as recited in claim 19, wherein the detecting comprises: comparing a change in the graph to a record of the first plurality of questions; and determining, based on the comparing, whether a node corresponding to the first plurality of questions was affected by the change. 23. A method as recited in claim 22, wherein the comparing comprises comparing a newly added link in the graph or newly added binary information on a node to the record. 24. A method as recited in claim 23, wherein the determining comprises checking whether the response, the created nodes, the created links, the created binary information, or the questions asked for one of the first plurality of questions would have been different if the newly added link had been in the graph when the response was provided. 25. A method
