Existing Features
 * can import data from .json or .csv format files
 * can import data from del.icio.us
 * can create and modify data programmatically
 * can bind data to dojo.widget.Chart
 * can bind data to dojo.widget.SortableTable
 * can bind one data set to multiple widgets
 * notifications: widgets are notified when data changes
 * notification available per-item or per-resultSet
 * can create ad-hoc attributes
 * attributes can be loosely-typed 
 * attributes can have meta-data like type and display name
 * half-implemented support for sorting
 * half-implemented support for export to .json
 * API for getting data in simple arrays 
 * API for getting ResultSets with iterators (precursor to support for something like the openrico.org live grid)
 
~~~~~~~~~~~~~~~~~~~~~~~~
To-Do List
 * be able to import data from an html <table></table>
 * think about being able to import data from some type of XML 
 * think about integration with dojo.undo.Manager
 * think more about how to represent the notion of different data types
 * think about what problems we'll run into when we have a MySQL data provider
 * in TableBindingHack, improve support for data types in the SortableTable binding
 * deal with ids (including MySQL multi-field keys)
 * add support for item-references:  employeeItem.set('department', departmentItem);
 * deal with Attributes as instances of Items, not just subclasses of Items
 * unit tests for compare/sort code
 * unit tests for everything
 * implement item.toString('json') and item.toString('xml')
 * implement dataProvider.newItem({name: 'foo', age: 26})
 * deal better with transactions
 * add support for deleting items
 * don't send out multiple notifications to the same observer
 * deal with item versions
 * prototype a Yahoo data provider -- http://developer.yahoo.net/common/json.html
 * prototype a data provider that enforces strong typing
 * prototype a data provider that prevents ad-hoc attributes
 * prototype a data provider that enforces single-kind item
 * prototype a data provider that allows for login/authentication
 * have loosely typed result sets play nicely with widgets that expect strong typing
 * prototype an example of spreadsheet-style formulas or derivation rules
 * experiment with some sort of fetch() that returns only a subset of a data provider's items
