Detailed Description

CTxMemPoolEntry stores data about the corresponding transaction, as well as data about all in-mempool transactions that depend on the transaction ("descendant" transactions).

When a new entry is added to the mempool, we update the descendant state (nCountWithDescendants, nSizeWithDescendants, and nModFeesWithDescendants) for all ancestors of the newly added transaction.
