Wow, I am just starting to realize that this IDLanROI object is going to
change a lot of things in my programs!

But, as far as I understand the documentation, it only stores one
entity. So, if I have many entities (often the case in my shapefiles), I
have to instance many IDLanROI objects, generate a mask for all of them
and then combine the masks together? Or did I miss something again?

Thanks!
