/ is not required at the end of the user-defined path

[mingchen-NOAA]

Pull Request Summary

Improved the user-defined directory feature that '/' is not required at the end of the paths.

Description

This pull request addresses an issue with path handling in user-defined directories. The trailing '/' is now optional when users specify their own paths. ww3_shel.F90 has been modified to handle user-defined paths with or without a trailing '/' correctly. model/nml/ww3_shel.nml was updated to provide an example configuration.

Issue(s) addressed

Improving PR #1369 to address issue #1221

Commit Message
