Write a simple primer to phyloreferencing as a blog post or page

[gaurav]

As we get more people asking us about phyloreferencing, it'd be useful to have a page to point them to with a simple but detailed and well-illustrated explanation of what phyloreferencing is and what it can provide. The closest we have right now is our blog post on A Phyloreferencing Experiment or the products page, but the former is out of the date and the latter doesn't have this information yet.

Now might not be the best time to do this, as exactly how phyloreferencing works will likely continue to change over the next couple of months. But I wanted to file an issue so we remember to do this eventually.

I think it would be more useful to say what a phyloreference is - how you can tell whether something is a phyloreference, their types/parts/properties/relationships, and so on. This might be done separately from discussion of phyloreferencing (shouldn't that be phyloreferring?), whatever that is, or together.
