- added new data structure 'eco' for an index file that should use only 50% of write-IO compared to kelondroFlex
The new eco index is not used yet, but already successfully tested with the collectionIndex
The main purpose is to replace the kelondroFlex at every point when enough RAM is available.
Othervise, the kelondroFlex stays as option in case of low memory (which then can even use a file-index)
