We have a trait TychoEncoder and then two implementations: TychoRouterEncoder and TychoExecutorEncoder. This way we go a level above with the decision if it is a direct execution or if it should use the tycho router. - Created two builders: one for each tycho encoder - Delete ExecutorStrategyEncoder and move code straight into the TychoExecutorEncoder - Add validate_solution to trait TychoEncoder - Move group_swaps.rs a level up - Update tests and usage cases Doing this we get rid of all that weird stuff we were doing before --- don't change below this line --- ENG-4306 Took 2 hours 6 minutes Took 12 seconds
