// 'controlsFXSpec' value to represent what we require. In other
// words, ControlsFX 8.0.0 has controlsFXSpecVersion of 8.0.0, so it will work on
// JavaFX 8.0.0 and later versions. Conversely, ControlsFX 8.0.6_20 has a controlsFXSpecVersion of
// 8.0.20 (controlsFXSpecTitle of Java 8u20), which means that ControlsFX will only work on JavaFX 8u20
