mdds 0.5.3
* mixed_type_matrix
* re-implemented the filled storage for better performance, with two
separate implementations for zero and emtpy matrix types. The
newer implementation should improve object creation time
considerably.
mdds 0.5.2
* flat_segment_tree
* fixed a crash on assignment by properly implementing assignment
operator().
* fixed several bugs in shift_right():
* shifting of all existing nodes was not handled properly.
* leaf nodes were not properly linked under certain conditions.
* shifting with skip node option was not properly skipping the
node at insertion position when the insertion position was at
the leftmost node.
* implemented min_key(), max_key(), default_value(), clear() and
swap().
* fixed a bug in operator==() where two different containers were
incorrectly evaluated to be equal.
* added quickcheck test code.

* flat segment tree
* segment tree
* rectangle set
