 * ETreeShowerPainter: class description
 * This class is responsible for reading tracks from the euso simulation tree
 * and doing its graphycal representation. It can draw the EUSO Field of View,
 * display 3D tracks, draw histogramms with Energy, Theta, Phi and X1 (more tome 
 * come) and even make the animation of 3D tracks and histogramms
