In face of this known issue, .joins(...).preload(...) felt like a slightly better option (vs. :select option passed to .near()) for just the particular use case I'm up against where includes would have been useful. 

Thought it'd be worth adding to the docs, especially as preload() isn't widely demonstrated in Rails own docs.

This is too much detail for the top of the README.

https://github.com/alexreisner/geocoder/issues/477

Add Rails 4 and Ruby 2.

Tweaks to wording in section on forward and reverse geocoding for coordinates that do not have known location addresses associated with them.

No longer do we install libs as plugins.

Make Geocoder.configure accept a hash (now preferred) and add
Geocoder.config method (for reading config). Deprecate old syntax.

Document uninitialized constant error with Mongoid.
