added cppStringList to allow creation of multi-line string literals using c++ literal concatenation ("line1\n" "line2\n" ...)
the reason for method is clang-format was having trouble with the multiline literal char const* s = R"(....)". Turns out it was likely somehow related to to the LLVM style used by clang-format because changing it to style=Google fixed it. So, the method exists and will remain in case needed elsewhere.
