Changed the doc class generation to individual files per class. It is also possible to save module files in module directories and the build system will

recognize them.

+		AStar class representation that uses vectors as edges.
+	</brief_description>
+	<description>
+		A* (A star) is a computer algorithm that is widely used in pathfinding and graph traversal, the process of plotting an efficiently directed path between multiple points. It enjoys widespread use due to its performance and accuracy. Godot's A* implementation make use of vectors as points.
+		You must add points manually with [method AStar.add_point] and create segments manually with [method AStar.connect_points]. So you can test if there is a path between two points with the [method AStar.are_points_connected] function, get the list of existing ids in the found path with [method AStar.get_id_path], or the points list with [method AStar.get_point_path].
