/**
 * Complement class to {@link jetbrains.mps.workbench.goTo.ui.MpsPopupFactory}, with dialogs to support common tasks to pick a model/module/node.
 * To decide whether you should use a dialog or a {@linkplain jetbrains.mps.workbench.goTo.ui.MpsPopupFactory#createPackagePopup(MPSProject, ChooseByNameModel, String) pop-up}
 * to pick a value, consider context of the activity. If you're inside a dialog/wizard, do not use pop-ups to enter values. If there's more than one input value,
 * prefer dialogs (although you can use components that behave similar to pop-ups, {@link jetbrains.mps.workbench.goTo.ui.MpsPopupFactory#createPanelForPackage(Project, ChooseByNameModel, boolean)} ).
 * If you need an input for a modification action, pop-up might be not the best option either.
