<h3>
Description:
</h3>
A reference vector of a lattice l \subsetR^n is
a vector v\in Rotimes_Z l. If the reference vector
is set, we will enumerate points in v-l. Typically it
is used to find points with minimal distance to the
reference vector.

<pre>

kash> Lambda := Lat(MatId(Z, 2));;
kash> LatEnumRefVec(Lambda, LatElt(Lambda, [1.7, 3.4]));
[1.7 3.4]

kash> LatShortestElt(Lambda);
> [ [ 2 3 ]
