/*
 
DEPRECATION:

on June 2021 this module was definitely abandoned due to efficiency
considerations and architectural issues.
 
it's now fully replaced by virtualknn2
 
this skeletal implementation is still preserved just to avoid
problems when connecting any DB-file created by previous versions
containing VirtualKNN tables.

/*
 
IMPORTANT NOTICE:

a similar module (VirtualKNN) was supported by previos versions.
 
this is a full replacement based on a completerly different algorithm
and presenting a substantially different interface.

now a MaxDistance Radius is absolutely required and the algorithm
has the capability to automatically expand it when required.
