+Add `Import#json`, `Export#json`, and `Export#email` (#34).
+
+The `#json` interface for importing and exporting JSON have been designed to work the same way they already work for the CSV interfaces. For example:
+
+```ruby
+json_string = [
+ {
+ email: "george@vandelay_industries.com",
+ password: "bosco"
+ }
+].to_json
+
+result = ArtVandelay::Import.new(:users).json(json_string, attributes: {email_address: :email, passcode: :password})
+```
+
+`ArtVandelay::Export#email_csv` has been changed to a more-generic `ArtVandelay::Export#email` method that takes a new `:format` option. The new option defaults to `:csv` but can also be used with `:json`. Since the old `#email_csv` method no longer exists, you'll need to update your application code accordingly. For example:
+
+```diff
+-ArtVandelay::Export.email_csv(to: my_email_address)
++ArtVandelay::Export.email(to: my_email_address)
+```
