// This will dump to the serial output a grid map of the defined mosaic
// The output is displayed as row column labeled grid with the NeoPixelBus
// index of the pixel at the intersection of the row and column.
//
// To help with physical layout, there maybe included a symbol following the index
//   <  means the index is the input index for the panel, the first on the panel
//   >  means the index is the output index for the panel, the last on the panel
//
// This is useful in visualising the mosaic layout of your panels to
// confirm you have them correctly wired together for this mosaic pattern
//
// It does not require that you have the actual panel connected
