multTableOneOne(...,Compact=>...) -- an optional argument for multTableOneOne that prints dots below the diagonal

Description

The default value of Compact is false. Changing the value to true saves space by printing dots for the products $e_ie_j$ for $i>j$

i1 : Q = QQ[x,y,z];
i2 : A = resLengthThreeAlg freeResolution ideal (x^2,y^2,z^2)

o2 = A

o2 : QuotientRing
i3 : multTableOneOne (A, Compact => true)

o3 = {{ , e , e , e }, {e , 0, f , f }, {e , ., 0, f }, {e , ., ., 0}}
