- Introduced Unit Testing capabilities to the PathFinder trait and algorithm.

Introduced also a small Unit test project to prove it.

- Separated caching capabilities from PathFinder class to increase cohesion and maintainability.
Refactored the pathfinding algorithm by extracting methods based on responsibilities like
calculating costs and reordering functions. These changes should provide a in average a small increase in
pathfinding performance and maintainability.

- Optimized the pathfinder algorithm to reuse calculations like the
MovementCost and heuristics.

- Introduced base classes, IPathSearch and IPriorityQueue interfaces,
and restructured code to ease readability and testability

- Renamed the PathFinder related classes to more appropriate names. Made the
traits rely on the interface IPathfinder instead of concrete PathFinder
implementation.

- Massive performance improvements

- Solved error with harvesters' Heuristic

- Updated the heuristic to ease redability and adjustability. D can be
adjusted to offer best paths by decreasing and more performance by
increasing it

- Refactored the CellLayer<CellInfo> creation in its own Singleton class

- Extracted the graph abstraction onto an IGraph interface, making the
Pathfinder agnostic to the definition of world and terrain. This
abstraction can help in the future to be able to cache graphs for similar
classes and their costs, speeding up the pathfinder and being able to feed
the A* algorithm with different types of graphs like Hierarchical graphs
