[IBM] Rectilinear - add fine granularity. Lets the user choose between coarse (bounding box) and fine (blanking zones) granularity for the rectilinear meshing. #196

See title. Coarse granularity: use bounding box & is most efficient for large areas Fine granularity: use IBC blanking and is best for targeted areas that stretch out over large areas. This is for areas that are ill-represented with bounding boxes.

In the figure below, if for the selected zone (blue base) we are looking to have a rectilinear in this region only fine granularity is to be preferred. Coarse granularity will create a bounding box around this area and therefore perform rectilinear in undesired areas - i.e. a bounding box cannot be used to properly represent the areas of interest. image

In the figure below, coarse granularity is preferred as we are targeting a large area that can be properly represented with a bounding box. image
