Make a rectangular grid

A rectangular grid can be created for every model supported by Delft Dashboard. The basic procedure will contain of three step.

1) All the relevant variables (grid orientation, resolution) is loaded from the interface in Dashboard (so-called handles).

2) Creation of a full grid based on the active bathymetry (often GEBCO '08). This full grid will have a margin of 20 percentile (is larger than the grid defined in Dashboard) in order to overcome interpolation issues. This full grid will also have a bathymetry in order to determine where the grid needs to be cut-off based on the maximum height (Z Max) described in Dashboard. This step is carried out by the function ddb_ModelMakerToolbox_makeRectangularGrid.

3) The final grid is created based on this larger grid. Rotation is taken into account and cells above a certain threshold (Z max) are deleted.  This step is carried out by the function MakeRectangularGrid.

function can be called by ddb_ModelMakerToolbox_Delft3DFLOW_generateGrid,
% ddb_ModelMakerToolbox_Delft3DWAVE_generateGrid, and ddb_ModelMakerToolbox_DFlowFM_generateGrid
% First a larger grid is made which is later used in MakeRectangularGrid
% The larger model used ddb_getBathymetry to get 'active' bathy
