Cross reference from iterarors/itertools to iterors • iterors

If you are coming from packages iterators/itertools/itertools2, all functionality should be preserved, but some may be under different names. Here’s a short transition guide:

iterators/itertools	iteror function
`iterators::iapply(array, margin)`	`iteror(array, by=margin)`
`iterators::recycle`	`i_recycle`
`itertools::ifilter(pred, iterable)`	`i_keep(iterable, pred)`
`itertools::ifilterfalse(pred, iterable)`	`i_drop(iterable, pred)`
`itertools::isplitCols(obj, ...)`	`iteror.array(obj, by="column", ...)`
`itertools::isplitIndices(n, ...)`	`icount(n, ...)`
`itertools::isplitRows(obj, ...)`	`iteror.array(obj, by="row", ...)`
`itertools::isplitVector(n, )`	`iteror.default(n, ...)`
`itertools::product`	`igrid`
`itertools::recycle(iter)`	`i_recycle(iter)`
`itertools::recycle(function() {...}, times=N)`	`iteror(function() {...}, count=N)`
`itertools::timeout(secs)`	`i_timeout(secs)`
`itertools2::icompress`	`i_mask`
`itertools2::icount(start=1, step=3, stop=15)`	`iseq(from=1, to=15, by=3)`
`itertools2::icycle`	`i_recycle`
`itertools2::idropwhile(pred, iterable)`	`i_dropwhile(iterable, pred)`
`itertools2::ifilter(pred, iterable)`	`i_keep(iterable, pred)`
`itertools2::ifilterfalse(pred, iterable)`	`i_drop(iterable, pred)`
`itertools2::ilength`	`count(obj)`
`itertools2::imap(f, it)`	`i_apply(it, f)` or `i_map(f, it1, it2, ...)`
`itertools2::ipairwise(it)`	`i_window(it, 2)`
`itertools2::iproduct`	`igrid`
`itertools2::irep_len`	`i_rep(length.out=n)`
`itertools2::iseq_len`	`icount`
`itertools2::iseq_along(x)`	`icount(length(x))`
`itertools2::itakewhile(pred, iterable)`	`i_keepwhile(iterable, pred)`
`itertools2::itripletwise(it)`	`i_window(it, 3)`
`itertools2::iunique_lastseen()`	`i_dedup()`

Other notes:

checkFunc arguments have been removed; instead use i_keep().
