numRowsPerFace numRowsPerFace 
The number of rows of streams per face of a cube around the Sun.
This is combined with the columns per face to decide how many total streams will be in the heliosphere. More total streams more heavily populates the space with nodes. Setting rows and columns to odd numbers ensures that there is a stream coming directly from the center of each face of the cube. int 3 1 9
