* an amount proportional to the percentage of total shares they were assigned. The distribution of shares is set at the
* time of contract deployment and can't be updated thereafter.

* `PaymentSplitter` follows a _pull payment_ model. This means that payments are not automatically forwarded to the
* accounts but kept in this contract, and the actual transfer is triggered as a separate step by calling the {release}
* function.
*
* NOTE: This contract assumes that ERC20 tokens will behave similarly to native tokens (Ether). Rebasing tokens, and
* tokens that apply fees during transfers, are likely to not be supported as expected. If in doubt, we encourage you
* to run tests before sending real value to this contract.
