Material Design TextArea Skin for android
* The JFXTextAreaSkinAndroid implements material design text area for android
* when porting JFoenix to android using JavaFXPorts
*
* Note: the implementation is a copy of the original {@link com.jfoenix.skins.JFXTextAreaSkin JFXTextAreaSkin}
* however it extends the JavaFXPorts text area android skin.
