Issue overview

An "orphan" ConnectorList object that is unconnected to any other objects does not give an error or warning message. You can paste the following into any input file:

ConnectorList,
Heating Supply Side Connectors, !- Name
Connector:Splitter, !- Connector 1 Object Type
Heating Supply Splitter, !- Connector 1 Name
Connector:Mixer, !- Connector 2 Object Type
Heating Supply Mixer; !- Connector 2 Name

and run it without errors, even though neither of the two referenced objects exist. I tried an "orphan" BranchList object and it correctly raised errors.
