Interface: new button to load Cameroon example
If a user wants to play with the Cameroon data included in the package, he or she needs to know where to find the relevant files, which are somewhat "hidden" in some obscure place within the installed packages' directory.
In order to facilitate and encourage the use of the example data, we could display a button "Load Cameroon example" in the "Files" tab, as an alternative to loading the user's own data. When clicked, all the relevant files should be automatically loaded, or at the very least, the pop-up window for loading files could be opened at the relevant directory.
