See https://www.klayout.de/forum/discussion/1247/renaming-layers-in-python-script#latest

This code does not do what it is supposed to:

current_view = pya.LayoutView.current()
i = 1
for layer in current_view.each_layer():
  layer.name = "LAYER" + str(i)
  i += 1

Fixed #276 (Layer properties name cannot be updated)

In addition, this fix includes Python-related fixes: because
of the short lifetime of Python references, the functionality
was not as expected sometimes. Keeping copies of LayerPropertiesIterators
helped. Some tweaks were required to maintain the delete() semantics.
