I created a TokenPaymentSplitter smart contract, which is similar to the existing PaymentSplitter smart contract except it works with ERC20s instead of Ether.
I published a tutorial on it so anyone can recreate it and integrate it into their own projects.

I would really like to know if OpenZeppelin would be interested in reviewing this contract and including it in their contracts repo in the Finance folder.
