This is an example of a simple feature plugin which adds two menu items.  
One menu item is added to the edit menu which opens a "Hello World" dialog.
The second menu item is added to the tools menu which displays the number 
of DrawnComponents contained in each open view of the current model in the
MessageWindow.
 
To build and install the plug-in, change the snapinstalldir variable located
in build.xml to point to your snap installation directory.  Running ant should
create the plugin and place it in the plugins directory.

Note: ant can be downloaded from http://ant.apache.org/.
