A function complex_to_normal_mode
was added in the tools.py
module (commit 0689cdd).
According to [1], the normal mode shape is the real part of the complex mode shape, when it is rotated so that the norm of its real part is maximized.

Great @klemengit In the last commit 87f1643 I added it also as a method!
