 As discussed in the literature above, we want to find a "changeless" solution.  A changeless solution is one that exceeds the `target` however is less than `target` + `cost_of_change`.  If no changeless solution can be found, then creating a change output by splitting a UTXO is the next best outcome.  To that end, `select_coins()` initially attempts a Branch and Bound selection algorithm to find a changeless solution.  If no changeless solution is found, then `select_coins()` falls back to a Single Random Draw selection strategy.

 ### performance comparison
 
 A basic performance comparison between this Rust BnB implementation and [Bitcoin Core](https://github.com/bitcoin/bitcoin/blob/4b1196a9855dcd188a24f393aa2fa21e2d61f061/src/wallet/coinselection.cpp#L76) using commodity hardware (My rather old laptop).
