+	test plan:
+	1) Ensure default constructor creates an object that return 0/false for property methods and throw tc::ObjectDisposedException for actions other than dispose
+	2) Ensure create constructor throw exceptions for all variations of bad input (empty list, a stream is null, the combination of streams did not at least all support read or write)
+	3) Ensure create constructor works with valid combinations of input (and stream properties are correct)
+	4) Ensure that even valid streams, calling setLength() will throw tc::NotImplementedException
+	5) For streams that have unsupported features (as indicated with false results from canSeek() & canRead() & canWrite()), make sure the related methods (seek() read() write()) throw tc::NotSupportedException when called if unsupported
+	6) For streams that support seek(), seek is quite vital for the performance for ConcatenatedStream as it may do a map lookup to find the correct stream, but also has edge cases. This needs to gracefully handle unexpected errors and edge cases.
+	7) For readable streams (that support seek), ensure read works for various kinds of ConcatenatedStreams (including base streams that do not are not at position==0 when they are iterated too)
+	8) For readable streams (that do not support seek), ensure read works for various kinds of ConcatenatedStreams (including base streams that do not are not at position==0 when they are iterated too, this is an error state)
+	9) For writable streams (that support seek), ensure read works for various kinds of ConcatenatedStreams (including base streams that do not are not at position==0 when they are iterated too)
+	10) For writable streams (that do not support seek), ensure read works for various kinds of ConcatenatedStreams (including base streams that do not are not at position==0 when they are iterated too, this is an error state)
+	11) Quality of life: The intended use case for ConcatenatedStream is when stored in std::shared_ptr<tc::io::IStream>, if copy/assignment/move operators/constructors aren't deleted, do they work as intended, if not fix behaviour or delete method...
