Implement <disableVolume at <storage> #17
Description
After some discussions we found scenarios in which we could be interested to enable all the volumes of the detector except one. This is not possible right now.
Right now behaviour is that if we do not specify any active volume, all volumes will be marked as active, and we will register energy deposits at all volumes. If we define 1 or more active volumes then, only those specified volumes will be used to register energy deposits.
We could live with both approaches. But we should check only activeVolume definitions, or only disableVolume definitions are found in storage and apply one schema or the other depending on which keyword we are using.
