Interferometer should be traces even with maxtem off
At the moment Finesse does not detect unconnected optical elements, this is not crucial but a trace when maxtem is off might help people finding typos in nod enames. Example code below.
from pykat import finesse
from pykat.commands import *
kat = finesse.kat()
kat.verbose = False
code = """
l laser1 1.0 0 n1
s s1 0 n1 n2
pd pow_t n2
m m1 1 0 0 n8 n9
xaxis laser1 P lin 0 1 10
yaxis abs
"""
kat.parseCommands(code)
out1 = kat.run()
