[Vala] Unmount disk using udisks2 objects in vala

[rastersoft <raster rastersoft com>]

Hi all:

I'm working with the udisks2 classes in Vala, and have the problem that 
I need to format a disk, but to do so, first I must unmount it. It seems 
that the only place where is an unmount method is in the Filesystem 
class, but I can't find how to create that class from a Block or Device 
class.

Can someone help me?

Thanks.
