if you declare InsertText(const std::string& text) {
 ...
}

gin will automatically convert the v8 args to string

same for the return value. If you return a vector<int>, it'll automatically be
translated to a v8 array

you can't know for sure that frame exists at this point. If you restructure the
CL to match my latest cl, you would forward this to a central object that always
has the right frame.

+  WebString text(WebString::fromUTF8(arguments[0].toString()));
