Add an Optional Offset to Capped Projections

[mcordingley]

It would be helpful if the capped projection could also take an additional option specifying how far to offset before returning items. This option would of course default to zero if not provided.

As an example, setting "cap" to 5 and not setting "skip" would have a projection that shows indices 0 - 4, inclusive. Setting "cap" to 5 and "skip" to 2 would show indices 2 - 6, inclusive.

It could be "skip", "offset", or whatever makes the most sense.

Thanks again.

Can we do it on top of FilteredCollection? Like providing a filter to skip items with index less than a desired value?

Then you can just combine such a filtered projection with CappedCollection.

Yeah, I think that would do it. The other way would be more convenient, but this keeps the core concepts purer, which is good.
