Some feedback from Oliver and Tim who have reviewed branch; give project and scheme different names, and change 'platform' to 'eegeo'. Scheme now called 'eegeo-sdk' and project 'eegeo-sdk-project'. Add a separate script to regenerate the xcode project -- this assumes the platform has been downloaded to the standard location already, and that the appropriate flag [-c] will be provided for the platform version. Rename the build folder from '/build.ios' to '/build'.
