// TESTING std::unique_ptr::unique_ptr()

// Concerns:
// 1 The default constructor works for any default constructible deleter types.
// 2 The stored type 'T' is allowed to be incomplete.
//
// Plan
// 1 Default construct unique_ptr's with various deleter types (C-1)
// 2 Default construct a unique_ptr with a incomplete element_type and
// various deleter types (C-1,2)
