KCLayout.cell(overwrite_existing) will make sure that when we are creating a new cell any pre-existing cell with the same name will be deleted.
WARNING: This might cause unwanted sideeffects like suddenly deleted references etc if an overwrite was performed, as all those cells will be deleted and therefore any instance of them as well.
KCLayout.cell(layout_cache) will use the current KCLayout as its cache. This means if a cell is already existant in the layout, this will use that cell instead of creating one.
