    MAIN APP - START
    This app is broken up into two separate sections
        - retrieve show output information from a device within the device_info.csv
        - dynamically create .csv files for each device containing this information
    The following block of code handles the processing of data within the device_info.csv file.
        - open the file in read-only mode and store the session as a variable csv file
        - read through the data and store the information as variable reader
        - begin for loop

            The following block of code handles the building of the ssh session through Netmiko
                - pulls the hostname, username, and password from the .csv file
                - builds a dictionary with this informaiton
                - creates an SSH session and stores it as ssh_session variable
                - finds the hostname and replaces the # sign from the prompt
                - prints out to the console a bunch of pretty formatting to highlight what device we're 
                  currently iterating through.
                - grabs the output of a show cdp neighbor detail, only including relevant information
