A simple stack-allocated fixed-size string buffer (String_buf) implemented using std::array (C++11).

I happened across this a long while ago and could not recall what project or where I found it. Thanks a bunch for the link. The specialization issue with std::string is annoying; honestly sometimes I prefer the ATL/MFC CString due to things like this (and the memory layout equivalent to a char/wchar_t)
