Returns \(I(\){pt1,pt2} is a dominating set of the CS-PCD\()\) where the vertices of the CS-PCD are the 2D data set Dt),
that is, returns 1 if p is a dominating point of CS-PCD, returns 0 otherwise.
CS proximity region is
constructed with respect to the standard equilateral triangle \(T_e=T(A,B,C)=T((0,0),(1,0),(1/2,\sqrt{3}/2))\) and
with expansion parameter \(t=1\). Point, pt1, must lie in the first one-sixth of \(T_e\), which is the triangle with
vertices \(T(A,D_3,CM)=T((0,0),(1/2,0),CM)\).
ch.data.pnts is for checking whether points pt1 and pt2 are data points in Dt or not
(default is FALSE), so by default this function checks whether the points pt1 and pt2 would be a
dominating set if they actually were in the data set.

Gam2CS.Te.onesixth(pt1, pt2, Dt, ch.data.pnts = FALSE)Two 2D points to be tested for constituting a dominating set of the CS-PCD.
A set of 2D points which constitutes the vertices of the CS-PCD.
A logical argument for checking whether points pt1 and pt2 are
data points in Dt or not (default is FALSE).
\(I(\){pt1,pt2} is a dominating set of the CS-PCD\()\) where the vertices of the CS-PCD are the 2D data set Dt),
that is, returns 1 if {pt1,pt2} is a dominating set of CS-PCD, returns 0 otherwise
