* `<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">
* <md-icon md-svg-src="your/icon.svg"></md-icon>
