 *  Checkbox list is a wrapper class around 'Checkbox' component to simply assembly of multi choice
 * component
 *
 * In Addition it adds ability to work with complex object. PrimeNG checkboxes work only with
 * primitive values.
 *
 * @see {@link check-box/check-box.component.ts}
 *
 *
 * ### Example
 *
 *
 *    @Component({
 *       selector: 'showCheckBoxList' ,
 *       template: `
 *           <aw-checkbox-list [list]="checkBoxListValues" [selections]="selectedValues"
 *
 *            [name]="'myColors'" [formGroup]="formGroup" (onSelection)="onCBClick">
 *           </aw-checkbox-list>
 *       `
 *
 *       })
 *        class MyShowCLComponent
 *        {
 *            checkBoxListValues: string[] = ['blue' , 'red' , 'yellow' , 'orange' , 'white' ,
 *     'silver' , 'black' ,
 *            'Green' , 'Gray' , 'Navy' , 'Olive' , 'Aqua' , 'Purple'];
 *
 *            selectedValues: string[] = ['blue' , 'Olive' , 'Aqua' , 'Purple'];
 *
 *
 *            formGroup: FormGroup = new FormGroup({});
 *
 *
 *            onCBClick (event): void
 *            {
 *                console.log('onCBClick = ' + event);
 *            }
