 <description>

Computes the box order ideal of type D=[D_1,..,D_N]. The input is a list of integers D of length <ref>NumIndets</ref>(). The output is a list of terms sorted in ascending order with respect to the current term ordering. <itemize>

 <item>@param D List of integer values representing an exponent vector of a term. The order ideal spanned by the term represented by this exponent vector will be computed.</item>
 <item>@return A list of terms of the order ideal spanned by the term represented by the exponent vector D, sorted in ascending order w.r.t. the current term ordering.</item>

</itemize> <example> Use QQ[x,y,z]; BB.Box([2,1,1]);

[1, z, y, x, yz, xz, xy, x^2, xyz, x^2z, x^2y, x^2yz]
