Imported changes from CollectionView project.
Lots of changes… the tableView is being filled, but not yet by the actual classifier from the server.
Fixed Glyph members' type: must be int, not str, for nRows and nCols to be meaningful.
Now theClassifier from JSON should work to populate the collection view.
Refactoring
Deleted lots of commented code, since things are working now.
Refactored the outline view so that the symbolOutlineDelegate does all the handling of the symbolArrayController, including an initialize method and a close method.  symbolCollections follow the same pattern.
Implemented 'close' on the classifierTableView delegate.  It requires an outlet for the table view, which isn't a problem.
Cleaning
Separated out SymbolOutlineView and created SymbolTableView because I was mixing them up.
SymbolOutlineView is for the tree type view, which I'm not using yet.
