Gridding engine

The gridding engine in CLASS (command `XY_MAP`) is efficient partly because a single convolution kernel for a given location can be computed and used for all planes. This implies the innermost loop to be on channels (Velocity) and outer loops on X and Y (Position). In other word, the convolution engine works with Velocity-Position arrays in memory (hence item 4 in table ).
