/** PndCaloDraw
 * @author T. Stockmanns
 * @since 26.3.2009
 *   Base class to display 3D Points in Eve as a BoxSet
 *   One has to overwrite the method GetVector which takes a TObject and writes out a TVector3 which is then taken as an input
 *   to place the points.
 *   If one wants to change the color of the points one has to overwrite the method GetValue. This method takes a TObject and
 *   an integer and translates this into an integer as input for the EveBoxSet method DigitValue
