/**
 * This class provides a full implementation of a {@link Property} wrapping a
 * {@link javafx.collections.ObservableMap}.
 *
 * The value of a {@code MapProperty} can be get and set with {@link #get()},
 * {@link #getValue()}, {@link #set(Object)}, and {@link #setValue(javafx.collections.ObservableMap)}.
 *
 * A property can be bound and unbound unidirectional with
 * {@link #bind(javafx.beans.value.ObservableValue)} and {@link #unbind()}. Bidirectional bindings
 * can be created and removed with {@link #bindBidirectional(Property)} and
 * {@link #unbindBidirectional(Property)}.
 *
 * The context of a {@code MapProperty} can be read with {@link #getBean()}
 * and {@link #getName()}.
