The Values vector should only be accessed from the outside through the GetValue() function. The Points vector should only be accessed using the AddPoint(), RemovePoint(), .. functions. This helps maintain internal invariants (e.g. keeping Points sorted) and allows for future removal / lazy evaluation of Values. The size() of the vectors had been accessed from various parts of the code; the GetLength() (for Values) and GetCount() (for Points) member functions provide access to this information and are already part of the public API.
