Computes the power of the test in (7). For a given
mean and standard deviation of the logged data, and the sample size, this
program computes the power of the test in (7). Help8.pdf 

Computes the pvalue for testing the difference between
two lognormal means. Also, computes the confidence interval for the
difference between the means. Help9.pdf

testing the mean and parameters, comparing two means, two scale parameters
and for comparing two shape parameters.
