Location Class

Hi,

During the previous teleconference we decided to use the current "assertor approach" for the location: we will not pre-define the location instance to *always* be a bag but that it can be either single type or compound type (where more than one trigger constitute one occurence of a result).

Please find a quick draft below for discusion on tomorrow's call:
