Added NAMESPACE file to CRAN package ‘fExoticOptions’

[Prof Brian Ripley]

All packages installled under R >= 2.14.0 (and we are now at 2.15.2)
need a namepsace, but this package did not yet have one.  R CMD build
and R CMD INSTALL would add one, and we have now re-built your package
on CRAN to have such a namespace.

Please review the automatically-generated NAMESPACE file and improve
it as needed.

There may be other issues that need fixing: see the CRAN check logs at
http://cran.r-project.org/web/checks/check_results_NAME.html,
replacing NAME by the name of your package.
