/**
* This method accepts the name of a repository (as it appears in the CampaignProperties) and
* updates it by adding the additional mappings that are in <code>add</code>.
*
* <p>This method first retrieves the mapping from the AssetLoader. It then adds in the new
* assets. Last, it has to create the new index file. The index file should be stored in the local
* repository cache. Note that this function <b>does not</b> update the original (network storage)
* repository location.
*
* <p>If the calling function does not update the network storage for <b>index.gz</b>, a restart
* of MapTool will lose the information when the index is downloaded again.
*
* @param repo name of the repository to update
* @param add entries to add to the repository
* @return the contents of the new repository in uploadable format
