Automatc time step issues with griddim=1 #15

This problem occur when either x or y are stricly equal to 16, then the regression algorithm doesnt work and the timestep chosen become 0.0, preventing the model to start.

I think the reduction algorithm if flowed for small grids and slow for larger. Need to implement reduction #6 from Mark Harris or at least #3 to start with
