Why is this private?

[Randy Smith (Not in Mondays), 2012/08/13 18:57:49]

I didn't write the code, but I suspect the answer is "because it can be".  The
original is protected rather than private so that it can be overridden by
derived test classes, and this is a derived test class that doesn't have any
overrides, and the who point of this class is overriding this method, so
inheriting from this class (rather than CDMD) and wanting to override
ChooseDownloadPath() doesn't make much sense to me.  

Having said all that, it probably makes sense for it to be protected, just for
consistency with the base class.  My only hesitation is that the CL is just
moving stuff around, rather than changing functionality.  But I'll make the
change.
