Class Menus

ij/src/main/java/ij/Menus.java:53–1821

This class installs and updates ImageJ's menus. Note that menu labels, even in submenus, must be unique. This is because ImageJ uses a single hash table for all menu labels. If you look closely, you will see that File->Import->Text Image... and File->Save As->Text Image... do not use the same label.
