/**
 * @ngdoc directive
 * @name mdButton
 * @module material.components.button
 *
 * @restrict E
 *
 * @description
 * `<md-button>` is a button directive with optional ink ripples (default enabled).
 *
 * If you supply a `href` or `ng-href` attribute, it will become an `<a>` element. Otherwise, it
 * will become a `<button>` element. As per the
 * [Material Design specifications](https://material.google.com/style/color.html#color-color-palette)
 * the FAB button background is filled with the accent color [by default]. The primary color palette
 * may be used with the `md-primary` class.
 *
 * Developers can also change the color palette of the button, by using the following classes
 * - `md-primary`
 * - `md-accent`
 * - `md-warn`
 *
 * See for example
 *
 * <hljs lang="html">
 *   <md-button class="md-primary">Primary Button</md-button>
 * </hljs>
 *
 * Button can be also raised, which means that they will use the current color palette to fill the button.
 *
 * <hljs lang="html">
 *   <md-button class="md-accent md-raised">Raised and Accent Button</md-button>
 * </hljs>
 *
 * It is also possible to disable the focus effect on the button, by using the following markup.
 *
 * <hljs lang="html">
 *   <md-button class="md-no-focus">No Focus Style</md-button>
 * </hljs>
 *
 * @param {boolean=} md-no-ink If present, disable ripple ink effects.
 * @param {expression=} ng-disabled En/Disable based on the expression
 * @param {string=} md-ripple-size Overrides the default ripple size logic. Options: `full`, `partial`, `auto`
 * @param {string=} aria-label Adds alternative text to button for accessibility, useful for icon buttons.
 * If no default text is found, a warning will be logged.
 *
 * @usage
 *
 * Regular buttons:
 *
 * <hljs lang="html">
 *  <md-button> Flat Button </md-button>
 *  <md-button href="http://google.com"> Flat link </md-button>
 *  <md-button class="md-raised"> Raised Button </md-button>
 *  <md-button ng-disabled="true"> Disabled Button </md-button>
 *  <md-button>
 *    <md-icon md-svg-src="your/icon.svg"></md-icon>
 *    Register Now
 *  </md-button>
 * </hljs>
 *
 * FAB buttons:
 *
 * <hljs lang="html">
 *  <md-button class="md-fab" aria-label="FAB">
 *    <md-icon md-svg-src="your/icon.svg"></md-icon>
 *  </md-button>
 *  <!-- mini-FAB -->
 *  <md-button class="md-fab md-mini" aria-label="Mini FAB">
