This change reorganizes the `tx/transactors` directory for consistency and discoverability. There are no behavioral changes, this is a pure refactor. Underscores were chosen as the way to separate multi-words as this is the more popular option in C++ projects. Specific changes: - Rename all subdirectories to lowercase/snake_case (`AMM` → `amm`, `Check` → `check`, `NFT` → `nft`, `PermissionedDomain` → `permissioned_domain`, etc.) - Merge `AMM/` and `Offer/` into `dex/`, including `PermissionedDEXHelpers` - Rename `MPT/` → `token/`, absorbing `SetTrust` and `Clawback` - Move top-level transactors into named groups: `account/`, `bridge/`, `credentials/`, `did/`, `escrow/`, `oracle/`, `payment/`, `payment_channel/`, `system/` - Update all include paths across the codebase and `transactions.macro`

// a single TicketCreate transaction to not use more compute power than
|
|
// a single compute-intensive Payment.
|
|
//
|
|
// Timing was performed using a MacBook Pro laptop and a release build
|
|
// with asserts off. 20 measurements were taken of each of the Payment
|
|
// and TicketCreate transactions and averaged to get timings.
|
|
//
|
|
// For the example compute-intensive Payment a Discrepancy unit test
|
|
// unit test Payment with 3 paths was chosen. With all the latest
|
|
// amendments enabled, that Payment::doApply() operation took, on
|
|
// average, 1.25 ms.
|
|
//
|
|
// Using that same test set up creating 250 Tickets in a single
|
|
// CreateTicket::doApply() in a unit test took, on average, 1.21 ms.
|
|
//
|
|
// So, for the moment, a single transaction creating 250 Tickets takes
|
|
// about the same compute time as a single compute-intensive payment.
