---------------------------------
Issue Type: Improvement (was: Task)
> BKDWriter refactor: Group point configuration in its own class
> ---------------------------------------------------------------
>
> Key: LUCENE-9292
> URL: https://issues.apache.org/jira/browse/LUCENE-9292
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Ignacio Vera
> Priority: Major
>
> 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.
