which had been changed a few months back to remove the individual
cell count and only list the top level cell. The behavior has been
changed a bit so that "list" returns values for the top level cell
only, but "listall" returns a complete list. "drc list count total"
gives the DRC count for the top cell, but "drc listall count total"
gives the DRC count for everything (probably not very useful).
Also: Implemented a behavior by request to automatically removed
the (UNNAMED) cell whenever a new cell is loaded and the (UNNAMED)
cell has not been modified.
