[geometry][index]: error fixed in iterative spatial query visitor - because of the error, the first return value in the query performed for a tree with only one node (root==leaf) was omitted. iterative distance query visitor modified for consistency.
[geometry][extensions]: Added required includes to nsphere.hpp, missing if rtree.hpp wasn't included.
[geometry][index]: errors fixed in additional rtree utilities.
[geometry][index]: removed non-c++03 header from statistics additional utility
Move some template parameters from class level to function level in assign_value.
[geometry][index]test: added libs required by interprocess built by clang on windows.
[geometry][index]test: shared memory segment created only once to prevent race conditions
[geometry][index]example: added serialization preliminary test/example (not compiling since serialization is not yet implemented)
[geometry][index]: experimental rtree serialization support added.
[geometry][index]example: serialization example improved, linking test added to Jamfile.
[geometry][index]: serialization of node type removed - currently there are only 2 types which may be deduced from leafs_level, check of the number of loaded values added.
[geometry][index]: added names to serialized objects to support xml archives, fixed error in loading of rstar parameters.
[geometry][index]example: added serialization to xml archives.
Distance strategies no longer need to be parameterized with the point type(s).
