Cleanup network docs
Introduced the RKTableController component for iOS.

RKTableController provides a flexible, integrated system for driving iOS table views using
the RestKit object mapping engine. Local domain objects can be mapped into table cells within a
collection or presented for editing as part of a form. There are three flavors of table controllers
available:

* Static Tables: RKTableController can be used to render simple static tables that are composed of RKTableItems
presented in RKTableSections. Table items can quickly be built and added to a table without a backing model
or can have content object mapped into them for presentation.
* Network Tables: RKTableController can also render a table with the results of a network load. The typical use
case here is to have RestKit retrieve a JSON/XML payload from your remote system and then render the content into
a table.
* Core Data Tables: RKFetchedResultsTableController can efficiently drive a table view using objects pulled from a
Core Data managed object context. Typical use-cases here are for the presentation of large collections that are
pulled from a remote system, offering offline access, or speeding up a UI by using Core Data as a fast local cache.

RKTableController supports a number of bells and whistles including integrated searching/filtering and pull to refresh.
Reduce log level for a log entry in RKManagedObjectMappingOperation
Add online check to determine whether or not swipe to delete should be enabled
Add handling for animating out the empty item when going from an empty table to a populated table. Fixes an issue where table animation was breaking due to unbalanced insert/deletes when the emptyItem was showing before a table update.
Updated UI specs to use the new naming convention: tableViewModel->tableController.  This resolves 30 test failures.
Rudimentary cleanup on the table view example, just updating framework method names.
Added momentary/fixed state for table cell selection, useful for static main menu items.
Fix issue with cell reuse. Fix issue with cell reuseIdentifier not behaving according to header documentation. Fixed some issues with the tableController specs. Add a cellMapping property to control automatic deselection of a tableView cell
Remove mutual exclusion check between onSelectCell and onSelectCellForObjectAtIndexPath block callbacks
Remove cell param from cellMapping heightOfCellForObjectAtIndexPath block, to avoid issues with and infinite loop. Change a few form methods to comply with tableController nomenclature. Fix broken specs and issues with tableController naming conventions in UI specs.

This reverts commit 635e9820168f73c0c469666f62c3862436d44a32.
Added setObjectMappingForClass:

Since the objectLoader isn't exposed, we needed a way to apply object mapping by class to complement mapping by key path.
Added a delegate method tableControllerDidFinishFinalLoad:

The method name stinks, but we need a callback in didFinishLoad, one that gets called when done loading loading from Core Data, static, or from the network.
Added UI test case for setObjectMappingForClass:, to handle naked object loading in RKFRTC
Exposes removeAllSections:recreateFirstSection in RKTableController.h
Move a few methods from RKTableController to RKAbstractTableController and added their implementations in RKFetchedResultsTableController. Fixed a bug regarding cell reuse in RKFetchedResultsTableController. Added the ability to set the NSFetchRequest on the RKFetchedResultsTableController, instead of requiring that it be looked up in the RKManagedObjectCache via a provided resourcePath.
Fix issue with _arraySortedFetchedObjects in cases where updates were received via the NSFetchedResultsControllerDelegate and were being then not being applied to the sorted array
