Generic attribute trait for support description

This trait can be implemented for a given attribute in order to hint at which components of the map the attribute is bound.

§Example

Using the same context as the for the AttributeUpdate example, we can associate temperature to faces if we’re modeling a 2D mesh:

use honeycomb_core::prelude::{AttributeBind, AttributeUpdate, FaceIdType, OrbitPolicy};
use honeycomb_core::attributes::AttrSparseVec;

#[derive(Clone, Copy, Debug, PartialEq)]
pub struct Temperature {
    pub val: f32
}

impl AttributeBind for Temperature {
    type StorageType = AttrSparseVec<Self>;
    type IdentifierType = FaceIdType;
    const BIND_POLICY: OrbitPolicy = OrbitPolicy::Face;
}
