Updated VERSION file
Added support for "abstract class" fixes issue #93
Added PHP 5.5 as test environment
mv {tests/,}phpunit.xml{,.dist}
Fix some typos in readme
Added: Operations can now be orphaned/split (no parent @resource or @api required for duplicate entries). Orphans will then be resolved to existing operations with the correct @resource and @api tree, by their unique nickname.  This allows different aspects of the API to be defined in different comment blocks.
Attempted resync
Implemented @SWG\Partial. A way to split & reuse annotation snippets.
