KSCrashAdvanced.h is accessible by default

[SSheldon]

Starting in 0114ae0, only certain headers of KSCrash/Recording are marked as public. KSCrashAdvanced.h is not one of them. However, with #124, the headers are exposed publicly in the KSCrash/Recording/Advanced subspec, which is installed by default.

A fix here depends on whether or not KSCrashAdvanced.h should be accessible by default:

• if not, the advanced subspec should not be included by default
• if so, there's not much reason to have the advanced subspec; the files of it don't compile independently, and since they'll always be exposed they should just be public headers of KSCrash/Recording

I'm assuming the advanced functionality should be "opt-in", and not accessible by default? Pull request incoming.

Slightly related, if you try to use just the advanced subspec, like:

platform :ios, '8.0'
use_frameworks!

target 'PodsTest' do
  pod 'KSCrash/Recording/Advanced', :git => '[email protected]:kstenerud/KSCrash.git', :tag => '1.0.2'
end

Then you don't actually get the KSCrashAdvanced.h header, since it's not captured by anything's source_files.
