 (int kindOfDistance = 1) and COSINE distance (int kindOfDistance = 2)
 and the following similar distances: SQUARED (0) (the squared value of the 
 metric/euclidian distance, INV_COSINE (3) the inversted cosine (actually the sine) 
 distance which is simply 1-cos, and ANGLE_RADIANT (4) the angle between the objects
 related to zero coordinates in the actual n-dimensional euclidian coordinate system 
 (ARC COSINE in radiant between [0 ; pi]).</TD>
