In certain conditions a lookup returned [nil] instead of [], which
caused a Result object to be initialized with no data.

Allows custom handling of geocoding service connection problems.

Fixes #56

Was causing problems when installing with bundler from Git URL.

Instead use a proxy if http_proxy or https_proxy is set. Also revise
code style to be more consistent with rest of library.

Geocoder will try to use environment's http_proxy or https_proxy when doing lookups unless that behaviour has been disabled in the configuration

Specify path to VERSION file relative to lib/geocoder.rb.

Child classes didn't have access to parent's configuration. This is kind
of crude (if geocoder_options not defined, see parent) but it works.

Were not returning correct results for reverse or IP address geocoding.

Figures out whether query is an IP address so you don't have to.

Prevents things like: " , ,  , United States".

Show all globally-supported attributes in a table.

Also alias as #province and #province_code.

On input and output (expects/returns lon,lat instead of lat,lon).
