[Terrapreta] Charcoal Specification Development

[Sean K. Barry]

Hi Dave & Christelle,

Thanks very much for working with Christlle Braun on developing this, Dave.  I will look at it soon and let you know what I think.  What I think now, is that you two have invested a great effort to help all of us and I wanted to thank you both.

Regards,

SKB

  Here is first pass at a class model that describes the relationship
  between the various entities as I currently understand them.

  I tried to keep things simple by including an experiment log where
  most of the procedural details would be kept. This allows users to
  keep as little or as much data as they want without cluttering up the
  model with rarely-used properties. The same goes for the soil and char
  analysis parts; rather than try to think of all the possible
  characteristics that someone might want to collect data for, I've
  modeled it as a list of name-value pairs, with a free-form text field
  so that the user can provide details about the measurement.

  It didn't seem useful to parallel the PyrolysisMethod-PyrolysisEvent
  relationship on the cultivation side. Maybe I'm wrong about that?
  Would a generic 'method' of cultivation experiment make sense? It
  would help to standardize testing, but I'm not sure if it would end up
  being used in the same way unless it were pretty general, like 'small
  pots' 'large pots', '25 sqft plot', etc.

  Anyway, take a look and let me know what you think.
