mdds 0.5.4 released

I’m happy to announce that version 0.5.4 of Multi-Dimensional Data Structure (mdds) is available for download from the link below.

This release fixes several bugs in segment_tree and point_quad_tree, but other than that, no other changes are made since 0.5.3. If you use 0.5.3 and don’t use these data structures, then there is no reason to update to 0.5.4.
