Iteration ids are incorrect via API

Iterations are dynamically calculated and do not have a real "id" that doesn't change. We only added the "id" element equivalent to the iteration number so that ActiveResource will work at all. API users can retrieve all or a subset of iterations via the "group, limit and offset" parameters (see examples below).

You can find more information in the iterations section of the API help page http://www.pivotaltracker.com/help/ap....

#ActiveResource Examples
require 'rubygems'
require 'activeresource'

class Iteration < ActiveResource::Base
self.site = "http://www.pivotaltracker.com/services/v2/projects/:project_id"
headers['X-TrackerToken'] = 'TOKEN'
end

# retrieving all iterations
Iteration.find(:all, :params => {:project_id => PROJECT_ID})

#retrieving a subset of iterations via the limit and offset parameters"
Iteration.find(:all, :params => {:project_id => PROJECT_ID, :offset => 3, :limit => 2})

#retrieving a subset of the 'backlog' via the group limit and offset parameters"
Iteration.find(:all, :params => {:project_id => PROJECT_ID, :group => 'backlog', :offset => 1, :limit => 2})
