/**
 * @module ModelWrap
 * ModelWrap components provide a way to call methods on models directly from templates. This is done by yielding callMethod task to the wrapped component.
 *
 * @example
 * ```js
 * <ModelWrap as |m|>
     <button onclick={{action (perform m.callMethod "save" model "Saved!" "Errored!" (transition-to "route")}}>
 * </ModelWrap>
 * ```
 *
 * @yields callMethod {Function}
 *
