Naming inconsistency in parallel algorithms.

[taeguk]

There are naming inconsistencies in parallel algorithms.

F vs Pred

F -

hpx/hpx/parallel/algorithms/copy.hpp

Line 563 in 0f16de3

template <typename ExPolicy, typename InIter, typename OutIter, typename F,

Pred -

hpx/hpx/parallel/algorithms/copy.hpp

Line 354 in 0f16de3

template <typename InIter, typename OutIter, typename Pred, typename Proj>

My opinion - In many places, two namings are mixed and used. It seems better to using Pred consistently.

I'd be glad to accept a corresponding PR

@hkaiser Okay, I'll do that in July.

@hkaiser I have more confusions about naming.
RandomIt vs RanIter vs RandIter
ForwardIt vs FwdIter
Compare vs Comp

Even though this is trivial thing, it seems better that there is one consistent naming.
How do you think about it?

By all means, go for it. Thanks!

Which naming is better as you think?
RandomIt vs RandIter
Compare vs Comp

FWIW, we've mostly been using InIter, FwdIter, BidirIter, RanIter, OutIter, and Comp. In other places we've used Op or Pred. In the end it doesn't matter as long as it is consistent.

I think we can close this now. Feel free to reopen if there are still places where the names are inconsistent.
