// zap.h : declaration of the CZap class.  This class handles zapping the files
//          of a project off of which we're basing the generated custom
//          AppWizard The files are zapped into templates used by the generated
//          custom AppWizard.  Class and file names from the original project
//          are "macroized" so that the generated custom AppWizard will create
//          new projects with class and file names derived from the new
//          projects' names, rather than from the original project's name.
