Details:

Zplane.m

It doesn't correctly indicate multiple poles / zeros.
This is apparent in the demo, with the 'empty a' subplot only showing a single
pole at the origin. It seems this has been corrected before, but the original
code has not been removed and it over plots the new bit.

It doesn't use system 'colororder' 

I have attached my version that:
 does correctly identify multiple poles / zeros,
 marks close poles / zeros as multiples,
 and uses the system 'colororder'
