<!-- Provides either an ajax or non-ajax button to invoke a "remote method" or "web method" declared in the controller.
Web Methods provide support for the RPC model of client-server interaction, in contrast to the REST model. The
preference in Rails is to use REST as much as possible, but we are pragmatists, and sometimes you just to need a remote
procedure call.
The URL that the call is POSTed to is the `object_url` of `this`, plus the method name
`<remote-method-button>` supports all of the standard ajax attributes (see the main taglib documention for Rapid
Forms). If any ajax attributes are given, the button becomes an ajax button, if not, Rails' `button_to` is used, which behaves similarly to a standard link.
### Attributes
- method: the name of the web-method to call
- label: the label on the button
-->
