 //  SectionParser is an interface that can parse a given 'section' in init.

-//  You can implement up to 4 functions below, with ParseSection() being mandatory.
-//  The first two function return bool with false indicating a failure and has a std::string* err
-//  parameter into which an error string can be written.  It will be reported along with the
-//  filename and line number of where the error occurred.
