Field.real/imag copy arrays, contrary to documentation
import nifty as ift
a=ift.RGSpace(10)
f=ift.Field(a,val=1.+1j)
f.real.val+=2
f.imag.val+=2
print f.valThis prints '1+1j' as the field value, i.e. the manipulations of real and imaginary parts did not affect the original field. This seems to contradict the documentation, which states that the data is not copied.
