Overview

Response is a simple proxy class for easy value unpacking from an API response. It is constructed with a hash and proxies method calls on the instance down to keys in the underling hash.

## Usage

response = Button::Response.new( 

prev: 'https://bloop.net/?cursor=1989',
next: 'https://bloop.net/?cursor=1991'

, :a => 1, :b => “two”)

puts response.data puts response.next_cursor puts response.prev_cursor
