remove all mutable member variable and leave only one const_cast in the kd-kdtree private function
const_build. This function is called in const predicates when the tree is not already internally built.
The documentation has been update and a few typos fixed at the same time.
handle case when kdtree is empty for all 4 nearest neighbor search method
correct sort method of bounded_priority_queue (was sorting the complete vector even if not full)
==> fix the crash when k > nb input points
Modify test suite to handle these particular cases
Use the bounded_priority_queue inside Orthogonal_k_neighbor search
and K_neighbor_search, a maximum of code is now shared by these two classes.
This reduces computation time and memory needed.
Extend the interface: to save time the sequence k-nearest neighbors
can be sorted (default) or not.
Add a new test that ensures all methods find the same kth closest neighbor.
Update manual.
