''' This is the text frontend to impedance measurements using EiFraExp class.
To start it in interactive mode, go to the program folder and type 'impedance'. It will read
non-asked setting from eifra_cnf.py
Optional arguments:
?  Will show this message
mode='mode string' Will start this program in the mode 'mode'. Valid mode strings are:
    'i'  Interactive mode, (default)
    'q'  Quiet mode. Will read all data from config file.
    ! Note: if the cfg file is in the same directory, you can omit the path and specify only
    file name. Otherwise, write the entire path!
