General information
----------------------
  - This project is basically two programs, ConfigWriter and reader, and
    an init script

  - ConfigWriter edits the configuration used by reader

  - reader uses the user configuration to set recording parameters
    and then records using the nidaqmx api

  - reader is ran as an init script located at /etc/init.d/reader

  - To reload the configuration for reader you need to relaunch the program
    either by power cycling the cDAQ-9136 or restarting/stopping and starting
    the init process using /etc/init.d/reader start/stop/restart

  - To simplify commands for the user aliases are provided in a .profile file.
    This allows the user to access /etc/init.d/reader with reader-daemon, to
    access /home/admin/reader/reader with reader, and to access
    /home/admin/ConfigWriter/ConfigWriter with ConfigWriter

  - The folder structure for the cDAQ-9136 is hard-coded into reader
    and ConfigWriter, so if you reinstall everything be sure to place it like so

    |-- /
        |-- etc
            |-- init.d
                |-- reader
        |-- home
            |-- admin
                |-- .profile
                |-- ConfigWriter
                    |-- ConfigWriter
                |-- reader
                    |-- reader
                    |-- config
                        |-- config.ini
                        |-- quick-config.ini
                    |-- output

  - Also if you reinstalled be sure to install the FTP server and SSH server
    on the cDAQ-9136 using NI MAX. Also set the server time using NI MAX. It
    would be more accurate to connect the cDAQ-9136 to the internet and download
    a NTP client using the built-in package manager instead of manually setting
    the time.
