Made acklownedrementGenerator.rb executable using the "./acklownedrementGenerator.rb" syntax
prettified require statement
Changed script so it takes two input parameters: "path to Settings.bundle" & "path to license files"
Changed from 'puts' & 'exit' commands to 'abort' when not enough arguments are supplied, as this will also generate a build error in Xcode
Changed 'Run Script'  in Sample Project to supply the two arguments for the acknowledgementGenerator.rb script
