// Author(s):   sdf

// Contact(s):  sdf

// Date:                1998/09/11

// Version:             0.01

// Purpose:             Class to encapsulate filename operations (i.e. broadly on a file which probably do not involve opening

//              it).  Importantly, the + and += operators performs filename segment addition, making sure that only one '\\'

//                              comes between each piece.

//              Translated to wxWindows conventions by julians (in progress)

// Description: Interface of the filename class

// Requires:    

// Provides:    

// See also:    

// Known bugs:  

// Usage:
