This class defines a Property wrapping a long value.
The value of a LongProperty can be get and set with get(),
getValue(), set(long), and setValue(Number).
A property can be bound and unbound unidirectional with
bind(ObservableValue) and unbind(). Bidirectional bindings
can be created and removed with bindBidirectional(Property) and
unbindBidirectional(Property).
The context of a LongProperty can be read with getBean()
and getName().
Note: setting or binding this property to a null value will set the property to "0.0". See setValue(java.lang.Number).
