CustomSpellDialog
-------------------------------------------------------------------------
Shows how to implement a custom spell-checking modal dialog.

The C1SpellChecker control has a built-in modal dialog used to display
spelling mistakes and allow users to correct them.

The built-in dialog can be customized in different ways. For example, you can 
use the Options.DialogLanguage property to quickly localize dialog. Or 
create an instance of the C1SpellDialog class, modify its properties, and then
pass that instance in a call to the CheckControl method.

If you need more extensive customization, though, you can create your own 
spell dialog and use that instead of the built-in one. This sample shows how
to do this. Custom spell dialogs are Form objects that implement the ISpellDialog
interface.
