[feature request] md-checkbox-group to make checkbox work with reactive forms

feature request:

Implement <md-checkbox-group> element, which would work same way as <md-radio-group>

What is the expected behavior?

Introducing this element, would be great way to deal with reactive forms, in same way as with radios:

<md-radio-group [formControl]="myForm.controls['radio']">
      <md-radio-button *ngFor="let option of radioOptions" [value]="option"></md-radio-button>
    </md-radio-group>

component:

export class MyComponent implements OnInit {

radioOptions: RadioInput[] = [
    new RadioInput("name1", "value1"),
    new RadioInput("name2", "value2"),
    new RadioInput("name3", "value3")
  ];

radioInput: RadioInput = this.radioOptions[1];

constructor(fb: FormBuilder) {
    this.myForm = fb.group({
      "radio": this.radioInput,
    });
  }
}

For checkbox, we would do something like that:

<md-checkbox-group [formControl]="myForm.controls['checkboxes']">
      <md-checkbox *ngFor="let option of checkboxOptions" [value]="option"></md-radio-button>
    </md-radio-group>

component:

export class MyComponent implements OnInit {

checkboxOptions: CheckboxInput[] = [
    new CheckboxInput("name1", "value1"),
    new CheckboxInput("name2", "value2"),
    new CheckboxInput("name3", "value3"),
  ];

checkboxInput: CheckboxInput[] = [this.checkboxOptions[0], this.checkboxOptions[2]];

constructor(fb: FormBuilder) {
    this.myForm = fb.group({
      "checkboxes": this.checkboxInput,
    });
  }
}

What is the use-case or motivation for changing an existing behavior?

At this moment it is impossible to with checkboxes using reactive forms

Which versions of Angular, Material, OS, browsers are affected?

@angular2-material: 2.0.0-alpha.7-3, @angular: 2.0.0-rc.5 @angular/forms: 0.3.0

Why is this? I don’t see why a checkbox group would be necessary.
