List.h uses `std::array` as container, but is missing the `<array>`
include. Add it to make the header self contained.
The `memory` include is unused and can be removed.
Don't use relative imports like `../foo.h` as those depend on the
relative position of both files. Rather than that use imports relative
to the `src` directory, which explicitly is part of the include
directories.
