    Terrain
        2D matrix of integers representing the height of a map at each cell.

    Coordinate
        A tuple of two integers ``(x,y)`` representing a cell in the terrain.

    Path
        A list of coordinates in the terrain.

        It represents a measure of the cost of the path in steps and climbs.

    Path Finding Algorithm
        A function that receives a terrain and returns a valid path.
