Compute Median Survival

1	med.surv(x, conf = 0.95, digits = 3)

`x`	The data.
`conf`	Confidence level.
`digits`	The number of decimal digits.

This formulation was derived by setting the cumulative density function of the Weibull distribution to 1/2 and then solving for the value t. The delta method is employed to derive a standard error and confidence limits.

`Estimate`	The Estimate of median survival.
`SE`	The standard error for the median survival estimate.
`.95 LCI`	95% lower confidence estimate.
`.95 UCI`	95% upper confidence estimate.
