extract common core data into a separate repo

That way other people can leverage the data easily without pulling in the rest of this project.

Correct me if I'm wrong, but could they not also use this link (https://cdn.kastatic.org/ka-exercise-screenshots-3/types/problemTypes.json) in an AJAX request?

@MrMagma That gets us the KA content that's linked to a given standard. We also need the text for the standards themselves. My innovation here was to augment the raw standards text with a) simple titles and b) in-plain-English descriptions. In summary, I think there are three separate parts of our Common Core data:

1) https://cdn.kastatic.org/ka-exercise-screenshots-3/types/problemTypes.json so we know how KA-content maps to standards

2) A file that gives the official standards text (dunno if this exists somewhere or if we need to create it—the data in the current repo is NOT a faithful reproduction of the standards... my bad)

3) A file that layers on friendly titles and descriptions for each standard (only partially complete in our repo right now)

For #2, @MrMagma maybe you could look into getting the official standards text from somewhere. KA displays standards text on the page, so maybe we've already got it in a nice format somewhere.

For #3, I think that's on me to finish it out...

@camsc I've created a repo that should contain the official descriptions for all the standards in JSON format here, which should satisfy item 2 from that list. There may be a few inaccuracies, as I wrote a Python script to get the descriptions and the Common Core site messed it up a few times, but they should be minor and easily fixed.

Sorry for the crazy slow reply. This is great. No matter where we go with this project, this will be a useful foundational step.
