//       Class : PathReplace
// Description : This encapsulates the user's command-line request to
//               replace existing, incorrect pathnames to models and
//               textures from a file with correct pathnames.  It
//               corresponds to a sequence of -pr command-line
//               options, as well as the -pp option.
//
//               This can also go the next step, which is to convert a
//               known file into a suitable form for storing in a
//               model file.  In this capacity, it corresponds to the
//               -ps and -pd options.
