#310 closed enhancement (fixed)

have multiple resolution versions of quadtree stored at one time

Description

basically the quad tree will contain buckets containing different resolutions. the quadtree will still be built at full resolution (or whatever resolution is specified in the constructor. the user will be able to request buckets from subset that contain a lower resolutions. This will mitigate the fact that as buckets are chached as a whole the entire bucket must be cached to access only a single or few points.

the solution i plan to use is rather than having different point buckets each point bucket will contain multiple serlizedinnerbuckets each at a different resolution. a new attribute will be added to keep track of which resolution the pointbucket should behave as. the meta data returned from the point bucket will be changed based on which serilizedinnerbucket it is providing access to.

upon further investigation i can find no way to implement the above plan that doesn't require heavy rewrites of the cache minder class along with others.

joy, a way was found, in part due to the prior removal of the serilizedinnerbucket and moving from using boost to serialize to manually reading and writing data.
