Please consider adding a subspec to avoid the post_install step you suggest using for extensions

Description:

the suggestion to use a post_install step in https://github.com/OAuthSwift/OAuthSwift/wiki/Work-with-application-extension is a hack that is easily avoided with a subspec

something like this would do the trick:

s.subspec 'Extension' do |extension|
    extension.dependency 'OAuthSwift', s.version.to_s
    extension.compiler_flags = '$(inherited) -DOAUTH_APP_EXTENSIONS'
end

then to use an extension they just use pod OAuthSwift/Extension

good suggestion, never tested
