mean_miner.h & mean_miner.hpp

[asperks]

Well that's confusing. It looks like the .hpp file is there to replace the .h file, but unless you're going right through the code to change all references of the .h file to the .hpp file, that's going to be an issue, yes?

Right now the mean_miner.h is just an obsolete version of mean_miner.hpp,
and each is only referenced by the corresponding mean_miner.c(pp).

In any case, all the mean_miner files are work in progress and only visible in the
main branch for entertainment/educational purposes. Once mean_miner is in working condition,
I'll do some cleanups...
