[hwa] QED is missing at the end of proof environments
As I understand there should appear a \QED
at the end of \begin{proof} ... \end{proof}
environments. This is currently not the case and can be reproduced with the attached snippet using the currently current dev version (df1f2c066fd390ef5e3664980212614d1f47348c
) of the Homeworkassignment-template.
