@simmsa I probably wont be able to get to this in the near-term so I wouldnt count on it being in the upcoming release. I'll see if I can make progress in the next couple of weeks though. Feel free to take a stab at the remaining tasks if there is a big push to include this in the release.

@simmsa this PR is ready for review....two things i wanted to point out:

• idk if the tests for the plots are ideal, let me know if you think they will pose some sort of issues with the fig save and delete methodology
• i think we will also need to update the matlab toolbox install since this will introduce a new module that likely might not be in the Path directories
