[Terrapreta] Early Terra Preta Production

[Greg and April]

A fundamental problem with this, is the fact that original TP sample is 
hundreds ( perhaps a couple of thousand ) years old, and is going to be 
weathered to the Nth degree.

We can make some base line estimates, but, unless a piece of char is found 
encased in a sample of pottery we may never really know.
