Updates in test-ios-sofia-cli: renamed the higher level API module SipManager from SofiaSIP, introduced a delegate protocol to SipManager so that it can notify its delegate (i.e. View Controller) of SIP events using a familiar Apple design pattern. Exposed 'cancel' SIP functionality through SipManager; it was annoying not being able to cancel a call
Merge branch 'master' of https://github.com/Mobicents/restcomm-ios-sdk
Moved RestCommClient library project to GitHub
Updates in test-ios-client: introduced test-ios-client staging project where I will abstract Sofia SIP and SipManager to RestCommClient API
Updates in test-ios-sofia-cli: had forgotten to set the delegate and events didn't come through - fixes #4
