Iterators adaptors with associated read-only data.
Useful for naming the types of wrapped iterators by using function pointers or non-capturing closures.
```rust use context_iterators::*;
type Closure = fn(usize, &usize) -> usize;
type MappedIterator = MapCtx
let iter: MappedIterator = (0..10) .withcontext(42) .mapwith_context(|item: usize, context: &usize| item + *context); ```
The MappedIterator type can be used in contexts where a concrete type is
needed, for example as an associated type for a trait.
```rust
trait Iterable {
type Iter: Iterator
struct MyIterable;
impl Iterable for MyIterable { type Iter = MappedIterator; } ```
