Title: Make ResultSet Enumerable

Thus you can operate directly on ResultSet objects instead of needing to call `to_a` on them first all the time:

```ruby
class User < ActiveRecord::Base
reportable :registrations
end

stats = User.registrations_report(grouping: :weekly, limit: 12)
stats.last # => [Mon, 22 Oct 2012, 12.0]

# No partial humans :-)
stats.map { |date, value| [date, value.to_i] }

# With no block, get an Enumerator
stats.each # => #
```
