// Construct a processor of an "edit" form using the class interface to a
// mySQL table generated by buildClass
//
// Build a processor of an HTML form from a mySQL table description that uses
// a SQLData derived class to access the data for the form.
// The processor program generated will require tweaking in order
// to be complete. Experience shows that the generated processor form is
// about 80% of the work.
