This new version of the backend has several additional features (API-…

…calls), including

*  uploadTable
*  bulkUploadTables
*  extendedSearch (with correspondence-based results-extension)
*  getRepositoryNames

Another key feature, is that now you don't have to work with only one index. You can have several data-repositories, each with its own tables, indexes and correspondences.
If you upload a table or search for a table, you can choose which repository you would like to use.
