ERC223 and ERC20 token deposit pattern GAS calculations

The following contracts were executed in REMIX testing environment.

TestDeposit contract accepts a deposit of a token, records the value of the deposit to one uint256 variable and emits Deposit(...) event with the same uint256 value of the deposited amount.

To deposit ERC20 token to this contract and make it recognize the transfer a user needs to approve the amount of the deposit first and execute the ERC20deposit function in the TestDeposit contract which will execute transferFrom function in the token contract and withdraw the funds.

In order to deposit ERC223 token and make the contract recognize the value a user must simply transfer tokens to the TestDeposit contract address and token contract will notify the receiver automatically therefore approval is not needed.
