Bug fix #92 : Structure values where not rightsided when assigned to a variable
Bug fix : state comparison failed when the state machines are duplicated (for structure procedures).
This is a HaCK and should be removed (or will be unnecessary) when state machines and procedure are no more linked together (see bug report #80)

The fix consists of executing the rightside operation when needed (and keep the result for further use)
