// To do list:
//
// This whole class has evolved over a period of years and needs a ground-up rewrite.
//
// - Take all wallet-relevant data out of Transaction and put it into WalletTransaction. Make Transaction immutable.
// - Only store relevant transaction outputs, don't bother storing the rest of the data.
// - Only store relevant transaction outputs, don't bother storing the rest of the data. Big RAM saving.
// - Split block chain and tx output tracking into a superclass that doesn't have any key or spending related code.
// - Simplify how transactions are tracked and stored: in particular, have the wallet maintain positioning information
// for transactions independent of the transactions themselves, so the timeline can be walked without having to
// process and sort every single transaction.
// - Decompose the class where possible: break logic out into classes that can be customized/replaced by the user.
// - [Auto]saving to a backing store
// - just generally make Wallet smaller and easier to work with
// - Split data persistence out into a backend class and make the wallet transactional, so we can store a wallet
// in a database not just in RAM.
// - Make clearing of transactions able to only rewind the wallet a certain distance instead of all blocks.
// - Make it scale:
// - eliminate all the algorithms with quadratic complexity (or worse)
