/**
* Bridges OpenAPI {@link NavigationTarget} with IDEA's {@link NavigationItem}
* The only use left is one in {@code jetbrains.mps.idea.core.navigation.MPSIdeaGotoClassContributor}, where {@link NavigationItem} is
* needed for a {@link NavigationTarget}. Though use of {@link jetbrains.mps.workbench.choose.NodePointerNavigationItem} is possible,
* need to deal with {@link #navigate(boolean)} implementation anyway, so this class persists.
* XXX Perhaps, shall relocate next to its only client and become package-local?
* <p/>
* Generally, it's a bad idea to associate particular behavior (here, navigation) with a data model for element chooser, but AFAIK
* with {@link com.intellij.navigation.GotoClassContributor} there's no other way but to handle navigation here.
