We also update some copyright years and fix various comments so the header is the same across all of VILLASframework. * Harmonize comment and code-style Signed-off-by: Steffen Vogel <steffen.vogel@opal-rt.com> * Harmonize comment and code-style Signed-off-by: Steffen Vogel <steffen.vogel@opal-rt.com> --------- Signed-off-by: Steffen Vogel <steffen.vogel@opal-rt.com>
