//
// <etymology>
// From Measure and Frame
// </etymology>
//
// <synopsis>
// The <linkto class=MeasFrame>MeasFrame</linkto> class contains the 'when
// and where' of an observed Measure. Calculations to get the appropiate
// value (e.g. the Earth's longitude) from this frame for conversions are
// done in this class, together with all the caching of (intermediate) results
// that can speed-up calculations.<br>
// The MCFrame class is used by the individual measure conversion classes
// (see <linkto class=MCBase>MCBase</linkto> class).<br>
// </synopsis>
//
// <example>
// <srcblock>
// MEpoch my_epoch(Quantity(MeasData::MJDB1950,"d")); // an epoch
// MCFrame frame(my_epoch); // used in a frame
// frame.set(obser); // add observatory (an MPosition)
// MEpoch::Convert conv(my_epoch, MEPoch::Ref(MEpoch::LAST, frame));
// </srcblock>
// The <em>conv</em> conversion engine will (transpararently) use the MCFrame
// class in calls from MCEpoch (the time conversions), which will be called
// by the MEpoch::Convert () operator.
// </example>
//
// <motivation>
// To separate the frame calculations from the Measure containers, to enable
// e.g. Tables to have Measures.
// </motivation>
