    A script to benchmark the initial sync performance of Nylas Mail. To use,
    simply run the script after authing whatever accounts you wish to measure
    in your development version of Nylas Mail. The benchmarking script will
    clear all of the data except for your accounts and open and close Nylas
    Mail several times, printing out the number of messages synced after each
    iteration.
