Awesome, @MatteoSalvador! Does the workflow check for the license and fail if it's missing? Or automatically add the license if it's missing?

We could later move this to the .github repository so it applies to all projects in SimVascular.

Thanks @mrp089! For the time being, the workflow checks for the license and fails if it's missing (or does not perfectly respect the given template). I agree with applying this workflow throughout Simvascular.

@ktbolt do you have any comments on this MR? Otherwise I think it's ready to be merged!

@MatteoSalvador @mrp089 There are so many other things that need to be done and we are spending time and effort on something of such little importance.

[mrp089]

@ktbolt, happy to spend 5 s to click Squash and merge!

We need license headers to release svFSI+, like we have for all other solvers in SimVascular (@alisonmarsden, correct me if I'm wrong).

Great that @MatteoSalvador 1) took the initiative and added license headers, and 2) made sure all files in the future will have license headers.

@mrp089 I was not referring to 1) but 2).
