CPSolver Update: Simple Search, Linked Sections

Simple Neighbour: Assign
- when conflicts are provided, unassing the conflicting variables before assigning the given variable
- some constraints my provide different conflicts each time the conflicts are computed and may even return a different number of conflicts
  - this can cause issue when used during the HC/GD/SA phase (e.g., by the Suggestion selection) when the number of assigned variables cannot decrease

Simple Search: HC/GD/SA
- when max-idle is enabled and unassignments are not allowed (Suggestion.AllowUnassignments is false, which is the default)
  - when the number of unassigned classes increases (is above the number in best solution) > automatically restore best

Student Scheduling: Linked Section
- allow one class to be present in multiple Linked Classes distributions between the same two courses
- for example having Lec 1 - Lec 1 and Lec 1 - Lec 2, and Lec 2 - Lec 1 to allow any combination except of Lec 2 - Lec 2
  - or Lec 1 - Lec 1, Lec 2 - Lec 2, and Lec 3 - Lec 1 or Lec 2 (prohibiting Lec 1 - Lec 2 and Lec 2 - Lec 1)
