The COXAutoComplete class provided similar capabilities to the user
like IE addressbar. It will remember your last values you've entered in
the edit box (number of the values for a window you can set by 
SetDepth()) function. And while you are typing it will suggest you some values from your most recently used ones. 
To use this class you may have just one instance for you application.
Call Attach() function for every window you want to provide this
functionality. If you want to provide separate list of values for
the windows you should supply different names for every window in
Attach(). The data is persistent and will be saved in the registry.
You do not need call Detach() - it will be done on destruction.
To add value to the list you must call Complete() function telling
to the COXAutoComplete to add this value to the list.
Usually it will be when user pressed enter.
The class has two flags that define his behavior.
When you call Attach() if you set OX_AUTOCOMPLETE_LIST flag, it will
bring you list box to show you possible values.
If you set OX_AUTOCOMPLETE_APPEND style it will fill edit box 
with recommended value. By default all they are set on.
