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 


STANDARD JAVA CLASS MAPS 

sorted map
time   for TreeMap<byte[]> generation: 2110
time   for TreeMap<byte[]> test: 2516, 0 bugs
memory for TreeMap<byte[]>: 29 MB

unsorted map
time   for HashMap<String> generation: 1157
time   for HashMap<String> test: 1516, 0 bugs
memory for HashMap<String>: 61 MB


KELONDRO-ENHANCED MAPS 

sorted map
time   for kelondroMap<byte[]> generation: 1781
time   for kelondroMap<byte[]> test: 2452, 0 bugs
memory for kelondroMap<byte[]>: 15 MB

unsorted map
time   for HashMap<ByteArray> generation: 828
time   for HashMap<ByteArray> test: 953, 0 bugs
memory for HashMap<ByteArray>: 9 MB

* this might fix problems on windows systems
