/**
 * A helper class for implementing {@link com.balysv.materialmenu.MaterialMenuDrawable}
 * as an {@link android.support.v7.app.ActionBar} Compat icon.
 * <p/>
 * In order to preserve default ActionBar icon click state call {@link com.balysv.materialmenu.MaterialMenuBase#setNeverDrawTouch(boolean)}.
 * Otherwise, adjust your theme to disable pressed background color by setting <code>android:actionBarItemBackground</code>
 * to null and use <code>android:actionButtonStyle</code>, <code>android:actionOverflowButtonStyle</code> to enable other
 * menu icon backgrounds.
 * <p/>
 * Disables ActionBar Up arrow and replaces default drawable using {@link ActionBar#setIcon(android.graphics.drawable.Drawable)}
