// Implementation for TestByte. See the comments in TestByte.h
// For each of the `variable classes' (e.g., Byte, ... Array, ... Grid) you
// *must* define a ctor, dtor, ptr_duplicate and read mfunc. In addition, you
// must edit the definition of New<class name> so that it creates the correct
// type of object. for example, edit NewByte() so that it creates and returns
// a TestByte pointer (see util.cc).
//
// jhrg 1/12/95
//
// NB: It is no longer true that you must subclass the Byte, ..., Grid
// classes in order to use the DAP. Those classes are no longer abstract. For
// many client-side uses, the classes will work just fine as they are. To
// build a server, it is still necessary to subclass and define a read()
// method for each of the data type classes. 01/22/03 jhrg

// The NewByte `helper function' creates a pointer to the a TestByte and
// returns that pointer. It takes the same arguments as the class's ctor. If
// any of the variable classes are subclassed (e.g., to make a new Byte like
// HDFByte) then the corresponding function here, and in the other class
// definition files, needs to be changed so that it creates an instance of
// the new (sub)class. Continuing the earlier example, that would mean that
// NewByte() would return a HDFByte, not a Byte.
//
// It is important that these function's names and return types do not change
// - they are called by the parser code (for the dds, at least) so if their
// names changes, that will break.
//
// The declarations for these functions (in util.h) should *not* need
// changing.
