Inaccurate configuration example

[ydawei]

Default configuration:

  // Compiler options for C (e.g. ['-std=c99'])
  "clang.cflags": [],

  // Compiler options for C++ (e.g. ['-std=c++11'])
  "clang.cxxflags": [],

I might be too nitpicking, but it seems that the configuration json file does not accept single-quote string, i.e. the ['-std=c99'] and ['-std=c++11'] should be ["-std=c99"] and ["-std=c++11"] respectively.
