Auxiliary elements for collections

For traits, this crate provides a single method for each operation to achieve maximum flexibility and freedom instead of imposing abstract subsets.

Examples

```rust use cl_aux::*;

struct SomeCustomVector(Vec, Vec);

impl Length for SomeCustomVector { #[inline] fn length(&self) -> usize { self.0.length() + self.1.length() } }

fn main() { let v = SomeCustomVector(vec![1, 2], vec![3, 4, 5, 6]); assert_eq!(v.length(), 6); } ```
