Create an extractor template repository

[max-zilla]

Follow the instructions on how to use GitHub's template repository feature https://help.github.com/en/articles/creating-a-template-repository

The goal of this is to provide developers with a framework to help guide them toward following the consistent implementation of extractors.

This can include:

• use of terrautils and other support libraries
• test directory, etc.
• README
• extractor (Clowder) pieces vs. algorithm (science) pieces

First steps

• create a new repository as a template
• identify a prototypical extractor
• duplicate it and push to the template repository
• pull out the specific stuff
• add instructions
  • pointers to documentation
  • summary of the git workflow
  • pointers to other exemplar extractors
• and stubs for
  • documentation
  • science code
  • tests

push terrautils documentation to readthedocs moved to separate issue #588

In summary, this should embed all of the information currently contained in our documentation https://docs.terraref.org/developer-manual/developing-clowder-extractors in order to make it easier for authors to find, reference, and understand what is required.

• coincidentally GitHub announced formal support for a template repositories on the same day this issue was posted! https://github.blog/2019-06-06-generate-new-repositories-with-repository-templates/

• We should check out other template repositories to see what is available and learn from what other projects have done.

• We should get feedback from contributors including @ZongyangLi, @Andrewzhzy, @abby621, @Paheding ... comments welcome now, but especially after we have a first draft of such a template.

• I'd be happy to take a stab at some of the details once some of the structure is set up.
