create_raster

Create raster of equally spaced cells. The distance between centre of cells
in both x and y dimension is equal to <code>cell_size</code>.

Calculate Kernel Density Estimation (KDE) for spatial data.
The algorithm is inspired by the tool 'Heatmap' from 'QGIS'. The method is described by:
