Add describe_feature function which takes a feature and optionally custom, manually defined metadata and returns an English sentence description of what the feature is:

<Feature: value>: The "value".
<Feature: ABSOLUTE(value)>: The absolute value of the "value".
<Feature: sessions.device_name>: The "device_name" for the instance of "sessions" associated with this instance of "log".
<Feature: MODE(log.zipcode)>: The most frequently occurring value of the "zipcode" of all instances of "log" for each "id" in "customers".

Looking good to me - I will take another look tomorrow and dive a little deeper into the logic, and leave any additional comments then.

[thehomebrewnerd]

Just a few more suggestions for consideration. I don't think any of these are blocking issues though, and overall this looks good!

[rwedge]

I think it'd be good to add some examples of how to use this functionality to the docs.

Perhaps a brief example, similar to what we did with feature graphs, along with a guide entry about how the user can customize the descriptions?

[rwedge]

Looks good!
