Create a new plugin for Excel that allows users to retrieve data from the Pentaho platform using metadata based queries.

The plugin needs to:

Allow the user to connect and login to a Pentaho BI server
Retrieve the list of metadata models available to the user and let them pick one
Retrieve the details of the selected metadata model
Allow the user to select columns of data that they want to see
Submit the metadata-based query to the server and populate the sheet with the results
Save the connection and query information with the Calc sheet
Allow the user to refresh the data when a saved document is loaded
