Standard containers require the types they store to be copy constructible.
Your problem is with CStringArray, which hasn't got an accessible copy ctor
and is preventing instantiation of the default copy ctor for TESTLIST. You
might be able to write a copy ctor for TESTLIST (BTW, all caps
conventionally names a macro) that uses CStringArray::Copy, or you might
simply use std::vector<CString> as a substitute for CStringArray.
