BindingListExample with sorting on multiple properties

I needed to have support for sorting over multiple properties (i.e. in SQL
it would be SELECT * FROM TABLE ORDER BY X, Y, Z) within a BindingList. So
I put together a sample BindingListExample that supports sorting, with
direction, on multiple properties of data objects in the list. The
IBindingList and the PropComparer implementation was based off of work by
John Vottero, see reference. Essentially I hijack the
IBindingList.ApplySort and ignore the PropertyDescriptor and
ListSortDirection parameters in favor of pulling the parameters from a
ListDictionary that contains the properties to be sorted on as keys, and the
direction as the values. An expanded PropComparer, PropComparerList, cycles
through the supplied ListDictionary until it reaches the end or the return
value is not 0.

Question, comments or suggestions can be sent to hollywood@thzero.com (or
