IntervalSets.jl and UnitRanges

Both represent some intervals with `start`

β `end`

.

Both support operations on sets: `in`

, `union`

, `intersect`

, and so on.

UnitRanges define indexing and iterator interface, which is not true sot IntervalSets, but it *can* be used for indexing with proper `toindex`

transformation (see for example SampledSignals.jl indexed in seconds interval).

IntervalSets can have infinite elements. Ranges are always finite and have an optional `step`

parameter, that defaults to one. But IntervalSets are also finite for some types, like `ClosedInterval{Float64}(1,3)`

) β then itβs similar to `1:3`

range.

So, looks like IntervalSets is an abstraction over UnitRanges for intervals of infinite number of elements?
