A podspec for IIIAsync

IIIAsync.podspec

Pod::Spec.new do |spec|
  spec.name         = 'IIIAsync'
  spec.version      = '0.2.0'
  spec.license      = { :type => 'MIT' }
  spec.homepage     = 'https://github.com/stevestreza/IIIAsync'
  spec.authors      = { 'Steve Streza' => '[email protected]' }
  spec.summary      = 'Concurrency control flow system for Objective-C'
  spec.source       = { :git => 'https://github.com/stevestreza/IIIAsync.git', :commit => '4e403e1a27542b7fa5defd49416d30930eb3b540' }
  spec.source_files = 'IIIAsync/IIIAsync.{h,m}'
  spec.requires_arc = true
end

I had to add the line spec.platform = :ios, '6.0' to get the library to compile. Otherwise dispatch_queue_t will not support ARC and the "retain" property attribute will throw a compile error.
