/* \class TESession
    \brief The TESession class is a combination of TEPTy and Emulations.

    Sessions are combinations of TEPTy and Emulations.

    The stuff in here does not belong to the terminal emulation framework,
    but to main.C. It serves it's duty by providing a single reference
    to TEPTy/Emulation pairs. In fact, it is only there to demonstrate one
    of the abilities of the framework - multible sessions.
