C++: Step 3 of the std::string transition. Convert the class overrides to use std::string instead of char*. Implement functions that take arrays of strings to std::vector<std::string>. Begin converting dwtestoo to use std::string instead of C style strings. Temporarily rename C style Connect functions to have a C at the end. It isn't clear to me why, but clang is telling me they are ambiguous. Even though the lambda explicitly specifies std::string it can't decide between the std::string or char* versions of the functions.
