Requests are divided into two locations; we are adapting current sorting methods to this criterion.
- Sort by width: take the average of the two time windows (pickup and delivery)
- End: take the end of the delivery
- Start: take the start of the pickup
- Distance: take the average of the two locations

- add sorting based on demand
- add sorting based on nearest and furthest
- add sorting based on time window

- replace template by switch case for the sorting strategy and the enumeration strategy in reconstruction operator
- remove generator / modficiation generator

- add enumeration of all Insert position for a pair
- add shuffle strategy

- add shuffle as basic sorting strategy
- add getter  to Solution
