How to use:

1-Create a class that inherits vptree.Point
2-Create vptree.VPTree
3-Add points to VPTree by using VPTree.addPoint
4-Call VPTree.mount
5-Search points near to a point of interest by using VPTree.searchNodes, this method returns nodes that contains points.
6-For each node, get the points by calling vptree.Node.getPoints.

Restrictions:
1-You can add point to the tree, but can not remove them
2-After you mount the tree, the statistics will not be calculated again. If the tree becomes unbalanced, you must recreate it.

Use vptree.VPTree.calculateStats.toString() to check the statistics.
