// <reviewed reviewer="Wim Brouw" date="2004/04/01" tests="tLSQFit, tLSQaips"

// </reviewed>
// <synopsis>
// The following classes are used in detremining the type of iterator
// presented to the LSQFit class. They are for a large part based on ideas by
// Alexandrescu(2001), 'Modern C++ design'.
// </synopsis>
// <example>
// See <linkto class="LSQFit">LSQFit</linkto> class, especially the
// <src>LSQFit2.cc</src>
// defintion file.
// </example>
// <motivation>
// To ease the interface to Fitting (and probably other) classes, by producing
// a framework that can be used with Casacore containers.
// </motivation>
// <todo asof="2004/04/01">
// <li> Add more type info if and when needed
