`step_trait` is required for marking the generic `Item` as iterable.
See the requirement for `RangeInclusive::into_iter`.

The main structure this crate provides is `PorousRange`, which abstracts over an indefinite amount of ranges (i.e. requires allocation) to simulate one non-contigous one.

`PorousRange` accepts any inner generic `item` that is `num_traits::One`, `core::iter::Step`, `core::marker::Copy`, `core::ops::Add`, and `core::ops::Sub`. These requirements are fulfilled by every built-in integer.

An `item` is never contained in more than one inner range and can be removed, if it is contained, so that range is removed and up to two new ranges are pushed so that `PorousRange`<sup>n</sup> \ `PorousRange`<sup>n + 1</sup> = { `item` }.
