Fastlib tree now is OT-compliant, meaning it can be serialized/unserialized. However, it still does not admit a bounding box of general primitive type (for example, a short-int based bounding box rather than a double-based bounding box), which would involve making changes to bounds.h, math/math.h:DRange class.

Last generation of the Krylov subspace based method has been caught - the bug was due to reusing the same dual-tree computation function across three different phases (some phases were required to use squared kernel values, rather than the regular values)

The naive code had a bug in computing the influence value of a point; it should have computed t(q)^T (B^T W(q) B)^{-1} t(q) W(0), instead of t(q)^T (B^T W(q) B)^{-1} t(q)

Fixed a bug in the dense version of the algorithm which did not shuffle the computed magnitude of weight diagrams and influence values accordingly due to the query tree construction; also there was a logic mistake in the design of the code which assumed that under variable-bandwidth case, the epanechnikov moment computed for the denominator matrix could be used for the weight diagram matrix, but this is not true since the effective normalization constant for weight diagram matrix requires squared normalization constants
