Abstract:

    Declaration of class CFtasrDlg

    This class provides a GUI interface for the FTASR process.
    It also implements the 3 main FTASR operations:
        "register"  - register FTASR as a BackupRestore command
        "backup"    - save the current FT hierarchy state in dr_state.sif file
        "restore"   - restore the FT hierarchy as it is in dr_state.sif file
