orbiter 4ff742e42d implemented indexCollectionRI
this is the new database structure that is supposed to replace the
plasmaAssortmentCluster AND the plasmaWordIndexFileCluster
The new structure is not yet active and needs to be integrated into
plasmaWordIndex. This has some migration constraints that are not yet
completely solved.

/* A kelondroIndex is a table with indexed access on the first column
Elements may be selected from the table with logarithmic computation time
using the get-method. Inserts have also the same computation order and
can be done with the put-method.
The kelondro Database provides two implementations of this interface:
kelondroTree and kelondroHashtable
