Ember computed property based validation library

import EmberValidator from '@eflexsystems/ember-tracked-validations/-private/ember-validator';

/**
 *  <i class="fa fa-hand-o-right" aria-hidden="true"></i> [See All Options](#method_validate)
 *
 *  If `true` validates that the given value is a valid collection and will add `<ATTRIBUTE>.[]` as a dependent key to the CP.
 *  If `false`, validates that the given value is singular. Use this validator if you want validation to occur when the content of your collection changes.
 *
 *  ## Examples
 *
 *  ```javascript
 *  validator('collection', true)
 *  validator('collection', false)
 *  validator('collection', {
 *    collection: true,
 *    message: 'must be a collection'
 *  })
 *  ```
 *
 *  @class Collection
 *  @module Validators
 *  @extends Base
