Issues/error with some examples

[bvernoux]

I have built pyopenems with Ubuntu 18.04 LTS 64bits like described in #6
But I have some issues with some examples (I doubt it is related to my build)

• pyopenems/examples/lpf_6.py

Traceback (most recent call last):
  File "lpf_6.py", line 39, in <module>
    box_width = 1.8*mm)
  File "/home/hydra/pyopenems/examples/openems/lpf.py", line 25, in generate
    l2 = l1.duplicate("line_p2").mirror('x')
AttributeError: 'Box' object has no attribute 'duplicate'

The same for

• pyopenems/examples/lpf_13.py

Traceback (most recent call last):
  File "lpf_13.py", line 40, in <module>
    box_width = 1.8*mm)
  File "/home/hydra/pyopenems/examples/openems/lpf.py", line 25, in generate
    l2 = l1.duplicate("line_p2").mirror('x')
AttributeError: 'Box' object has no attribute 'duplicate'

I removed the old low pass filters and plan to replace them with one derived from LPF_DGS_bowtie.py at some point. I'll leave this issue open to track that. Thanks for reporting.
