====== Qzz ======

###
The zz component of $Q$ is defined as:
\begin{equation}
Q_{zz} = 3z^2/r^2 - 1.
\end{equation}
The equivalent operator in Quanty is created by:
<code Quanty Example.Quanty>
OppQzz = NewOperator("Qzz", NF, IndexUp, IndexDn)
</code>
The operator could also be defined by:
<code Quanty Example.Quanty>
Akm={{2,0,2.0}}
OppQzz=NewOperator("CF",NF,indexup,indexdn,Akm)
</code>
