 *
 * Allows you to set a custom font to a button's text via XML.
 *
 * Start by adding xmlns:oak="http://oak/oak/schema" to the base of your view.
 * You can then specify a particular font with
 * oak:font="Your-font.ttf"
 *
 * Make sure the font you want to use is in a proper assets/fonts/ folder.
