// <etymology>
// MaskArrIO is short for MaskedArrayIO, which is too long by the old
// AIPS++ file naming conventions.  This file contains global functions
// for writing out ascii representations of masked arrays.
// </etymology>
//
// <synopsis>
// These functions write out masked arrays in ascii representation.
// They simply write out the Array and the LogicalArray which is the mask
// using the ascii output functions for these objects.
// </synopsis>
//
// <example>
// <srcblock>
//   Vector<int> a(10);
//   LogicalVector b(10);
//   MaskedArray m (a,b);
//      . . .
//   cout << m;
// </srcblock>
// This example writes out m in ascii.  It writes first a and then
// the mask constructed from b.
// </example>
//
// <motivation>
// These are primarily for debugging, so that one can examine the MaskedArray.
// Since MaskedArrays are manipulators of Arrays, it was not thought to
// be necessary, or even a good idea, to have other kinds of IO defined
// for them.
// </motivation>
