Overview

Keeps a stack of batches and helps out when Indexer is asked to batch documents.

If the client does something like 

Sunspot.batch do
  some_code_here
  which_triggers_some_other_code
  which_again_calls
  Sunspot.batch { ... }
end

it is the Batcher’s job to keep track of these nestings. The inner will be sent of to be indexed first.
