1140 6629 d 1 h jermar /kernel/trunk/generic/ Change B+-tree from 2-3-4 tree to 2-3-4-5 tree by adding space for the fourth key.
This should make key removal easier.		  
1136 6633 d 0 h jermar /kernel/trunk/generic/src/adt/ Try to avoid splitting full B+-tree nodes by trying left or right rotation first.
(This improved memory consumption of this algorithm by some 40% - meassured on 101-item set).		  
1134 6634 d 4 h jermar /kernel/trunk/generic/src/adt/ Change B+-tree to:
- store lesser keys in a key's left subtree
- propagate the bigger of medians (if there are two medians) when splitting a node		  
1121 6635 d 22 h jermar /kernel/trunk/ Small textual changes.  
1101 6638 d 23 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
