Mount an object or volume.
The object that should be mounted is inserted into the Object
attribute. If the object reside in the same project, or in a volume
that is loaded in the development environment, it can be specified
by name. Also specify the volume in the name, eg VolFurnish:H1-H2.
If the object reside in another project and the volume is not loaded,
it has to be specified by identity. Select the object in the configurator
and use command 'show objid' to get the identity.
For operator stations, it's common to name and place the mount object
so that the path of objects will be the same in the mounting volume
as in the mounted volume. Otherwise for example Ge graphs will not
work for both volumes.
