orbiter 9416f5c26f more speed test cases: kelondro provides map functions that are more than 20% faster than standard java classes and use less than halve of the memory of java classes: 
just start IndexTest (here with 1000000 test objects)

Performance test: comparing HashMap, TreeMap and kelondroRow
generated 1000000 test data entries
