Prints the value of all variables in this vector.  This
method is primarily intended for debugging OPeNDAP applications and
text-based clients such as geturl.

@param os    the <code>PrintWriter</code> on which to print the value.
@param space this value is passed to the <code>printDecl</code> method,
and controls the leading spaces of the output.
