Historic tuning modes

[Newton Hunt]

Hi Jason,

I downloaded the .pdf file and have looked at it but not studied it. 
Maybe the final version should have a "significant" category to help
determine it's historical significant.  Obviously 200 HTs would have
quite a few that were less significant than others in terms of who, when
and where they were used.

I just love making more work for others. :)
