/** Transaction flags.

    These flags are specified in a transaction's 'Flags' field and modify the
    behavior of that transaction.

    There are two types of flags:

        (1) Universal flags: these are flags which apply to, and are interpreted
                             the same way by, all transactions, except, perhaps,
                             to special pseudo-transactions.

        (2) Tx-Specific flags: these are flags which are interpreted according
                               to the type of the transaction being executed.
                               That is, the same numerical flag value may have
                               different effects, depending on the transaction
                               being executed.

    @note The universal transaction flags occupy the high-order 8 bits. The
          tx-specific flags occupy the remaining 24 bits.

    @warning Transaction flags form part of the protocol. **Changing them
             should be avoided because without special handling, this will
             result in a hard fork.**
