/**
* UI 2018 Buttons
*
* Four styles are include: basicButton, primaryButton, bigBasicButton, bigPrimaryButton.
*
* Buttons support passing in DomElementArgs, which can be used to register click handlers, set
* the disabled property, and other HTML <button> element behaviors.
*
* Examples:
*
* `basicButton('Basic button', dom.on('click', () => alert('Basic button')))`
* `primaryButton('Primary button', dom.prop('disabled', true))`
