Interface and implementation parameter mismatch

[AndyChappell]

There is a mismatch between the parameter names in the header declaration of Initialize and its source implementation. tpc and nhits are swapped. It's not immediately clear to me if this has implications at any call sites as currently implemented, it depends on the reference used by the caller, but this looks like an inconsistency needing follow-up.

Thanks for the catch @AndyChappell ! Not yet in use, so no further changes needed, but definitely worth fixing! Would you like to add the commit yourself?

Hi @mantheys, sure, I'll aim to get a PR in, in the next couple of days.
