// <etymology>
// MaskLogiArrayFwd is short for MaskedLogicalArrayForwards, which is
// too long by the old AIPS++ file naming conventions.
// It contains forwards for MaskedLogicalArrays.
// </etymology>
//
// <synopsis>
// This file contains forward definitions for MaskedLogicalArrays.
// </synopsis>
//
// <motivation>
// There are places where MaskedLogicalArrays cannot be defined, i.e. where
// MaskLogiArr.h cannot be included.  In those places, one must provide
// forward declarations for those objects which one is using.
// This is particularly tricky for MaskedLogicalArrays, since they are not
// classes, but are rather typedefs.  In order to make these forwards
// easier to get correct, and easier to maintain, this file was created.
// If MaskedLogicalArrays should ever be change to a class, only this file would
// need to be changed, instead of every file where the current typedefs
// would have to be changed to class forwards.
// </motivation>
//
// <todo asof="$DATE:$>
//   <li> Consider making these into classes.
//   <li> Consider replacing with builtin boolean class when that
//          makes it into the C++ compiler.
// </todo>
