rethink the info command
Right now the info command just gives you a list of available variables in a file. We can pretty easily organize a lot more basic information about the file contents (without actually looking at the data).
- show file info (dimensions, global attributes)
- show variable info (size/type, dims, attributes)
This will need to be implemented/tested for all the types of files Glance supports:
- netCDF (with and without groups)
