QRL Migration Splitter Script

/*
    QRL Migration Splitter

    This tool helps you protecting your privacy by suggesting how to
    migrate your ERC-20 QRL tokens into mainnet QRL before
    the end of the migration process on 28 Feb 2019.

    The idea behind this script is to hide your total holdings by
    splitting them in multiple addresses of your choice, each with
    a randomized migration date and held amount.

    After the script has run, a text based table will be printed
    on your console so that you can copy it and use it as a reminder.

    Instructions:
    1) Generate as many QRL addresses as you desire
    you can either use the online wallet at https://wallet.theqrl.org
    or the safer command line version https://github.com/theqrl/qrl)
    2) Fill the Configuration Section below according to your addresses
    and preferences
    3) Run this script in a javascript console.
    ( on chrome you can open it by left-clicking anywhere on any page,
    then select 'inspect' --> 'console' tab,
    paste this script in the console, press enter and you're done:
    you should now see a table with dates, amounts and the corresponding
    address to carry out the migration. )
