Add Shelley, and new window in HelloMixpanel for AB testing
Add function to call any selector with args on a path from a root view
move code over to Mixpanel.m, add a KVC setting function:
Execute a variant from a JSON object
Added check for pasteboard string on startup to see if we should be in A/B test mode
Add Shelley inline, concatenating all the Shelly filters into one h/m file
WIP: View Hierarchy data and screen capture to support A/B testing.

No tests. :(
Merge branch 'ab-object-selectors' into ab-testing

Conflicts:
	HelloMixpanel/HelloMixpanel.xcodeproj/project.pbxproj
	HelloMixpanel/HelloMixpanel/HelloMixpanel.storyboard
	HelloMixpanel/HelloMixpanel/ViewController.m
cleanup Shelley parser, remove shorthand class names, we will always use full class names
How did this get in here?
clear pasteboard after we detect AB testing token
Adding the AppCode project dir to the ignore file
Putting the all value transformers in the correct folder.
Adding SocketRocket code.
Renamed SRWebSocket files to MPWebSocket.
Renamed all symbols to avoid clashes with SocketRocket.
Missed renaming things in a couple spots.
Renamed MPFastLog to MPLog (there is nothing fast about it).
WebSocket code depends on icucore.
Removing unused function.  I guess once it might have been used by the log code.
