/*! \brief EacGLW is the QGLWidget of the Edit Atom Styles Dialog EacDlg. 
 * 
 * EacGLW displays a sp3 like molecule. The 'molecule' consists of a central atom with anisotrop ADP and a neighboring atom without ADP 
 * (displayed as a ball) both are from the same changeable type. Attached to the central atom are also 3 hydrogen atoms. The molecule 
 * rotates continously around its own axis which itself rotates as well. This widget demonstates the look and feel of an atom specific 
 * setting which can be changed in the EacDlg. 3 Q-Peaks are displayed arround the molecule.
