Installation error: implicit instantiation of undefined template

Issue summary

When running the installation instructions, I encountered the error error: implicit instantiation of undefined template 'std::basic_stringstream<char>' std::stringstream s;.

Proposed solution:

This was resolved by adding #include <sstream> to src/operation.h. I'd be happy to open a PR to add this, but I'm not sure what's the preferred contribution guideline.
