The Grid interpolator simply applies a linear interpolation between two grids on a cell by cell basis.
InterpolationIncrement i,j = EndYear i,j - StartYear i,j / ( EndYear i,j - StartYear i,j )
For each year between the StartYear and EndYear
CurrentYear i,j = StartYear i,j + ( InterpolationIncrement i,j * ( CurrentYear - StartYear ))
