/**
 *
 * Implements standard HTML radio button on top of PrimeNG with ariba styling
 *
 * ### Example
 *
 * 1. Basic usage using ngModel pre-selected first radio
 *
 *  ```ts
 *
 *      @Component({
 *          selector: 'demo-comp',
 *          template: `
 *              <aw-radiobutton [name]="'color'" [value]="'red'" [label]="'Red'"
 *                             [(ngModel)]="model">
 *             </aw-radiobutton>
 *              <aw-radiobutton [name]="'color'" [value]="'blue'" [label]="'Blue'"
 *                      [(ngModel)]="model">
 *              </aw-radiobutton>
 *      `
 *      })*
 *      class BasicWithNgModelComponent
 *      {
 *          model: string[] = ['red'];
 *
 *          constructor()
 *          {
 *          }
 *      }
 *
 *  ```
 *
 *
 * 2. Basic usage with formGroup
 *
 *
 * ```ts
 *       @Component({
 *           selector: 'demo-comp',
 *           template: `
 *          <div [formGroup]="env.currentForm">
 *               <aw-radiobutton [name]="'color2'" [value]="'red'" [label]="'Red'"
 *               (onChange)="onChange($event)">
 *               </aw-radiobutton>
 *               <aw-radiobutton [name]="'color2'" [value]="'blue'" [label]="'Blue'"
 *               (onChange)="onChange($event)">
 *               </aw-radiobutton>
 *
 *       </div>
 *       `
 *       })
 *       class BasicWithFormGroupComponent implements OnInit
 *       {
 *           model: string = 'blue';
 *
 *           constructor(public env: Environment)
 *           {
 *           }
 *
 *           ngOnInit(): void
 *           {
 *               this.env.currentForm = new FormGroup({});
 *               this.env.currentForm.registerControl('color2', new FormControl(this.model));
 *           }
 *
 *
 *           onChange(event: any): void
 *           {
 *               this.modelSet = event;
 *           }
 *
 *       }
 *  ````
