DistanceGrid implementation backed by an internal MapBasedGrid. Provides efficient distance-based neighbor searches using a multi-source BFS computed from all not-full cells. The distance map is lazily evaluated and cached to optimize repeated neighbor queries during flood propagation. Transparently exports properties and methods of the internal grid (width, height, getElementAt, elementsMap) for seamless integration with existing grid operations.
Lists cells that are not empty according to a presence criterion. For elements of type floodsim.model.cell.Cell this means water volume strictly greater than 0. Useful for identifying active flood areas and computing simulation statistics.

Returns neighbors of the coordinate that are not "full" per the filling metric. Searches at a dynamic radius based on distance to nearest not-full cell, optimizing neighbor discovery in sparsely flooded grids. Falls back to immediate (distance=1) neighbors if no not-full cells found at computed radius. For elements of type floodsim.model.cell.Cell, "not full" means the flooded percentage is less than 100%.

Returns a new grid with the element at the coordinate replaced, if the coordinate is inside bounds. If the coordinate is out of bounds, returns the same instance unchanged.
