IODA f90 interface

I see some PRs have been merged - is the process complete? Can it be used? Are there any examples to follow?

The process is complete is for now and there are some over simplified examples in the src/engines/Examples in the IODA source code. It can be used though it has not been tested throughly.
There is also an interface in the main directory that is used by most packages. It is simpler but there are only a few things you do with it. If you encounter problems feel free to ping me, @PatNichols . I wrote the ioda/engines code and would be happy to help/fix.
Thank you for your inquiry.
