Speed up CellLinked search

[gatocor]

There is a slow down happening because of the eraise and cumsum in CellLinked process.

# inside neighborsCellLinked
                    community.abm.neighbors.cellNumAgents_ .= 0
                    $namef($(base...),)
                    # community.abm.neighbors.cellCumSum_ .= cumsum(community.abm.neighbors.cellNumAgents_) .- community.abm.neighbors.cellNumAgents_
                    begin 
                        cumsum!(community.abm.neighbors.cellCumSum_, community.abm.neighbors.cellNumAgents_) 
                        community.abm.neighbors.cellCumSum_ .-= community.abm.neighbors.cellNumAgents_
                    end
                    $namef2($(base...),)

By computing cumsum inplace, I have reduced the memory overhead, but some additional speed up could be performed.
Maybe declaring a vector storing the grid points with cells to just clean those positions? It will require more memory but may speed up the cleaning process?
