/**
 * The AML Token
 *
 * This subset of BurnableCrowdsaleToken gives the Owner a possibility to
 * reclaim tokens from a participant before the token is released
 * after a participant has failed a prolonged AML process.
 *
 * It is assumed that the anti-money laundering process depends on blockchain data.
 * The data is not available before the transaction and not for the smart contract.
 * Thus, we need to implement logic to handle AML failure cases post payment.
 * We give a time window before the token release for the token sale owners to
 * complete the AML and claw back all token transactions that were
 * caused by rejected purchases.
