Make Port Connection Consistency mark missing connections

[brlarson]

The .csv spreadsheets are nice, but they don't tell what's not connected.
Put marker on contained component declarations, containing list of all ports of that component don't have connections. Similarly, for missing connections of containing component instance, put list at top of classifier

Please send a model as well as some indication for fixing your bug (what is missing, what do you expect, etc.).
Otherwise, I cannot reproduce it.

Thanks.
