Will be adapting alternate method for new BOD calculation. Currently assumes a data structure that is not needed. Will now calculate vectors for all particles and return as an array to the user to do with as they wish. This avoids any artifacts from assuming some kind of spherical coordinate histogram.

No demand for this. If someone wants this, it can be built later.
