@sbillinge ready to review. Mostly are made by the skpkg update command with minimal fix. In this PR:

1. Because we don't want to change license, I maintained the same one as before. And also the same for the license starting date. I manually add the starting year of license.
2. I realized that in the matlab code, one of the parameters should be called alpha instead of alph. Therefore, I changed that to the correct name.
3. To make it convenient to update, since originally we have the doc instead of docs, I first did a rename of the folder so that package update would identify the structure and do the update for the docs folder properly.
4. If this could be merged, I would do the pytest stuff to update the deprecation thing in the next PR.
