* the `md-primary` class.
*
* @param {string} ng-model Assignable angular expression to data-bind to.
* @param {string=} name Property name of the form under which the control is published.
* @param {expression=} ng-true-value The value to which the expression should be set when selected.
* @param {expression=} ng-false-value The value to which the expression should be set when not selected.
* @param {string=} ng-change Angular expression to be executed when input changes due to user interaction with the input element.
* @param {boolean=} md-no-ink Use of attribute indicates use of ripple ink effects
* @param {string=} aria-label Adds label to checkbox for accessibility.
* Defaults to checkbox's text. If no default text is found, a warning will be logged.
*
* @usage
* <hljs lang="html">
* <md-checkbox ng-model="isChecked" aria-label="Finished?">
* Finished ?
* </md-checkbox>
*
* <md-checkbox md-no-ink ng-model="hasInk" aria-label="No Ink Effects">
