progress on validating new Book record
Book record validation near complete, working on logic of new vs update
Books basically working
simplified code; removed references of any objects that don't need it
Book panel working, except for checking name conflict if edited
fixed bug where OnSelChange would fire twice on new record creation
check for conflict when changing Book name
maintain DataDates as a DB table rather than a view. Datasets panels load somewhat faster.
work on implementing Sheets in 'datasets.py'
Book and Sheet management basically working, still some bugs
Tree and Sheet working in 'datasets.py'
changes to 'OutputColumms' table structure in DB
in 'datasets.py', begin on implementing Columns
in 'datasets.py', progress on implementing Columns
renamed 'shPnlSiz' to 'colPnlSiz'; not necessary but helps track what class we are in
improved testing for None values in Column panel
change details based on Column Type, 1st steps
now shows Column Type 'Constant' correctly
more work on Column Types
more in Column Types, all except Aggregates
