When https://gitlab.science.ru.nl/clean-and-itasks/clean-graph-copy/merge_requests/2 is merged this will make sure that `symbols_in_program` is also present in the 64-bit windows distributions of GraphCopy. This module is needed to retrieve symbols from an executable which is needed for graph copying with names.
