TiltTempCovScale
[TauX,TauY,tvar] = TiltTempCovScale(lambda,D,G,Atm,[DispCov])
Computes the temporal covariance scale lengths for modeling Kolmogorov tilt fluctuations as a Markov random process in time. Returns temporal scale lengths and tilt variance quantities for modeling tilt temporal covariance as: $C_{X}(t,0) = tvar*exp(-t/TauX)$ and $C_{Y}(t,0) = tvar*exp(-a/TauY)$
