A test driven smart contract to split Ether and ERC20 tokens to a list of recipients and to simulate money stream during withdrawal

• I paid the gas fee using another recipient so as not to tamper with the withdrawal balance update after paying gas fee
• Recipient default balance was 100 ETH
• This makes it easier to test that the withdrawal amount is in the correct proportion
• I simulated the money stream by causing 1 second delay before every withdrawal in the test script however it took 2 seconds to complete withdrawal
• This means that I made withdrawal every 1 second but it took 2 seconds for the transaction to be processed, hence withdrawing at 2 seconds interval
• The withdraw log is present below the README.md. Each withdrawal is at 2 seconds interval
• Defence against reEntrancy attack was implemented for ether withdrawal. Test for this was successsful
• The ERC20 token contract was not written with so much security. The purpose was just to get started with an ERC20 contract for an integration test with the Payment contract
• My test values are from the PDF sent so it could be easy to see how well the code works with the test values
