Details:

inspired by bug #38063, attached is a working, matlab compatible version of
expfit for the statistics package.  It calculates the mean and confidence
intervals for the mean of a sample of exponentially distributed data, allowing
for right-censoring and adjustable sample frequency. 

extending a bit from matlab capabilities, this expfit allows you to use
censoring and frequency options with nD sample arrays, where matlab restricts
their use to sample vectors only.

added BISTs for most input and option combinations and errors. all tests pass
and help text renders without error. header text appears to match other
functions in the package, although it differs from core octave.

patch also updates Index.in and NEWS.

Note - as discussed in the mentioned bug report, this will create a namespace
collision with an expfit function in the optim package until that function is
renamed. 

m file attached. will make patch after getting a patch number.
