I updated cppcomponents after the CppNow 2014 presentation, but did not
update the examples. Thanks for bringing it to my attention.

To update this, in the inline id functions for example
inline std::string Command1Id(){return "Command1";}

change the return type to const char*

For cr_string, change to string_ref, and cr_wstring to wstring_ref

Let me know how this works.
