Description

In order to build a BKD tree, we need to provide  to the BKDWriter the point configuration we are indexing. That is the number of dimensions, the number of indexed dimension, the number of bytes per dimensions and the  max number of points per leaf. From this information, we actually derive some important parameters like the number of bytes per point

 

The idea of this change is to group all this information into its own class so we can share this information more easily with other objects.
